Why this matters

The extended absences of rising stars like Will Zalatoris and Jake Knapp highlight a shift in professional golf, where the pursuit of extreme driving distance is increasingly resulting in severe upper-body and joint injuries among younger players.

Key points

  • Will Zalatoris underwent surgery for a partially torn labrum in May and will miss the remainder of the summer schedule.
  • Breakout rookie Jake Knapp remains sidelined indefinitely with a severe left thumb sprain that has forced four consecutive withdrawals.
  • Marco Penge has taken an indefinite leave from the PGA Tour to recover from recurring vertigo and neurological symptoms.
  • Sports medicine experts attribute the rise in upper-body injuries to the extreme torque and deceleration forces of the modern golf swing.
  • Rehabilitation for these players will focus on strengthening stabilizing muscles to withstand high clubhead speeds.

PGA Tour starts for Zalatoris in 2026

The gruelling reality of the modern PGA Tour schedule has caught up with several of the sport's brightest young talents, as a wave of upper-body injuries forces extended absences midway through the 2026 season. While veteran stars often manage chronic back and knee issues, the current injury report is dominated by rising players dealing with acute joint and ligament damage. At the forefront of this attrition are Will Zalatoris and breakout rookie Jake Knapp, both of whom have seen highly anticipated campaigns derailed by severe upper-body setbacks. Their respective absences not only alter the competitive landscape for the summer's remaining signature events but also underscore the immense physical toll exacted by the contemporary golf swing.[1]

For Will Zalatoris, the 2026 season has become another frustrating chapter in an ongoing battle for physical durability. According to recent reports, the 29-year-old Dallas native underwent surgery in May to repair a partially torn labrum in his shoulder. The procedure effectively rules him out for the remainder of the summer, with his camp targeting a return during the fall portion of the schedule. Zalatoris had already been managing an ankle injury earlier in the year, which limited him to just four PGA Tour starts in 2026 and forced a withdrawal just before his first-round tee time at the Cognizant Classic.[1][2]

While the shoulder surgery represents a significant setback, those close to Zalatoris have expressed a measure of relief that the issue is not related to his spine. The young star previously underwent a microdiscectomy in late 2025 to address a herniated disc, a procedure that sidelined him for months and required a complete rebuild of his swing mechanics. The fact that his surgically repaired back has held up under tournament conditions is a long-term positive, but the cascading nature of his injuries—from back to ankle to shoulder—highlights the difficulty of maintaining elite form when the body is constantly compensating for weakened areas.[1]

Meanwhile, the PGA Tour has been temporarily deprived of one of its most exciting breakout stories. Jake Knapp began the 2026 season with blistering momentum, logging seven top-11 finishes in his first eight starts and averaging nearly 320 yards off the tee. His early-season dominance, which included a top-15 finish at the Masters and elite metrics in strokes gained, positioned him as a premier contender. However, his rapid ascent was abruptly halted by a severe left thumb sprain that flared up in late April.[2]

Knapp’s thumb injury has proven far more stubborn than initially anticipated, leading to a frustrating sequence of late withdrawals. After attempting to play through the discomfort, on-course reports indicated he was unable to swing a club without severe pain, ultimately forcing him to pull out of the Truist Championship with a heavily bandaged hand. The lingering sprain has since kept him out of four consecutive high-profile events, including the PGA Championship and the Memorial Tournament. With no official timeline provided by his coaching staff, Knapp remains sidelined indefinitely, leaving a significant void in the Tour's rookie class.[2]

The physical attrition on the Tour extends beyond orthopedic injuries, as evidenced by the recent absence of Marco Penge. The young professional announced he is taking an indefinite break from competition to focus on his health after battling recurring neurological issues. Following a severe viral infection late last year, Penge has dealt with chronic sinus infections and debilitating vertigo symptoms. Although recent MRI results came back clear, the lingering effects have made it impossible for him to compete at the highest level, prompting him to step away until he is fully fit.[2]

The concentration of upper-body and joint injuries among younger players has prompted sports medicine experts to scrutinize the biomechanics of the modern professional game. Historically, golf injuries were heavily concentrated in the lower back and knees, often the result of the classic "reverse C" follow-through. Today, however, the pursuit of extreme distance has fundamentally altered how force is generated. Biomechanists note that modern players keep their lower bodies incredibly stable and square to the target line, relying on massive upper-body torque to whip the clubhead through the impact zone at unprecedented speeds.

This single-side rotational force creates a violent kinetic chain that places immense stress on the shoulders, elbows, wrists, and hands. When a player generating 125 miles per hour of clubhead speed encounters the sudden deceleration of turf interaction, the shock is absorbed directly by the smaller joints of the upper extremities. Orthopedic specialists point out that hitting millions of golf balls with this high-torque, stiff-shafted modern swing pushes the human body to extremes rarely associated with the sport in previous decades, making labrum tears and thumb sprains an increasingly common occupational hazard.

To combat this epidemic of upper-body injuries, specialized sports medicine programs are emphasizing targeted preventative conditioning. Medical professionals working with elite golfers now prioritize strengthening the stabilizing muscles around the rotator cuff and the intricate tendons of the hand and wrist. For players like Zalatoris and Knapp, the rehabilitation process will require not just tissue healing, but a careful biomechanical assessment to ensure their swings do not immediately overload the repaired joints upon their return to competitive play.

As the PGA Tour heads into the grueling final stretch of the summer season, the absences of Zalatoris and Knapp serve as a stark reminder of the sport's physical demands. Both players possess the elite talent necessary to contend for major championships, but their immediate futures depend entirely on the success of their respective rehabilitations. For now, the golf world will have to wait until the fall to see if these sidelined stars can reclaim their trajectory and safely harness the explosive power that defines the modern game.[1]

Viewpoints in depth

Sports Medicine Experts

Medical professionals emphasize the biomechanical toll of the modern golf swing.

Orthopedic specialists and biomechanists argue that the modern pursuit of 330-yard drives has fundamentally changed the sport's injury profile. By anchoring the lower body and relying on extreme upper-body torque, players are subjecting their shoulders, wrists, and hands to violent deceleration forces upon turf impact. This single-side rotational stress makes labrum tears and ligament sprains an expected occupational hazard for today's power hitters.

Player Development Coaches

Coaches focus on balancing elite clubhead speed with long-term physical durability.

Swing instructors and player camps acknowledge the necessity of power in the modern game but stress the importance of sustainable mechanics. For players like Zalatoris and Knapp, coaches are increasingly prioritizing targeted strength training for the smaller stabilizing muscles of the upper extremities. The goal is to build physical resilience that can withstand the violent kinetic chain of a 125-mph swing without sacrificing competitive distance.
