Athletics shortstop Jacob Wilson is expected to miss the remainder of the 2026 season due to a recurring left shoulder injury. Manager Mark Kotsay confirmed the likely shutdown on Thursday, noting that the 24-year-old infielder is scheduled to be examined by a doctor in Sacramento ahead of an impending injured list placement.
Left Shoulder Injury Sidelines Wilson for the Remainder of the Season
The Athletics’ injury woes deepened on Thursday as manager Mark Kotsay announced that shortstop Jacob Wilson will likely miss the rest of the 2026 season due to lingering issues with his left shoulder, as reported by MLB.com. Wilson was scheduled to travel to Sacramento to be examined by a doctor to determine his next steps following the team’s 6-2 loss to the Kansas City Royals at Kauffman Stadium.
The 24-year-old infielder has not played since Sunday due to left shoulder soreness and was unavailable off the bench, according to Yahoo Sports. He is expected to be placed on the injured list prior to Friday’s series opener against the Houston Astros at Daikin Park.
“Unfortunately, this morning there was really no change in how he’s felt since Sunday. … At this point, probably not great news in terms of Jacob’s ability to finish the season.”

A Timeline of Setbacks Following a May Subluxation
Wilson’s physical troubles stem from a left shoulder subluxation sustained in May, when he made a diving attempt for an infield single hit by Gunnar Henderson. That initial incident forced him onto the injured list for a full month.
Upon returning to the lineup, Wilson encountered further misfortune, missing an additional 10 games due to right thumb inflammation. Even after working his way back, the shoulder continued to flare up, notably when he was unable to achieve full range of motion while swinging on Monday.
“He’s definitely been playing with his shoulder [injury] since he came back off the IL. We knew the shoulder, if he had to make another play, which he did in Boston [during Aug. 7-9], that it may come back and be an issue.”

Despite the physical toll, Wilson maintained a respectable presence on the field. Across 80 games this season, he compiled a slash line of .266/.298/.388 with seven home runs, 16 doubles, and 37 RBIs over 366 plate appearances. Those numbers represent a dip from his breakout 2025 All-Star campaign, where he batted .311 with 13 homers, 26 doubles, and 63 RBIs across 125 games. He also signed a seven-year, $70 million contract extension in January.
Mounting Injuries and Roster Fallout for the Athletics
The loss of Wilson compounds a brutal year of health setbacks for an Athletics squad sitting last in the American League with a 49-79 record. Kotsay pointed to a cascading series of absences that altered the team’s trajectory after a hot start that saw them spend 36 days alone in first place.
“We lost our leader and captain in Rook early in June, which impacted not just on the field, but I think off the field. … It seems to be kind of a domino effect with the rest of the group.”

Wilson joins a crowded injured list featuring several core players whose seasons are already finished. The team has lost first baseman Nick Kurtz (right thumb strain), catcher Shea Langeliers (torn meniscus), outfielder Tyler Soderstrom (left hip impingement), and designated hitter Brent Rooker (left knee surgery), according to Yahoo Sports.
Opportunities for Depth Pieces Moving Forward
With Wilson sidelined, the Athletics have turned to internal options to fill the void at shortstop. Kotsay noted that Alika Williams, Darell Hernaiz, and Max Muncy will see increased playing time alongside Donovan Walton as the organization evaluates its depth through the final weeks of the schedule.
Whether Wilson will require surgical intervention remains dependent on his upcoming medical evaluation in Sacramento, with recovery timelines carrying implications for his availability heading into next year’s spring training.
