Cardinals Rookie JJ Wetherholt Placed on Injured List With Wrist Tendinitis
St. Louis Cardinals rookie JJ Wetherholt has been placed on the 10-day injured list due to right wrist tendinitis.

St. Louis, MO, August 30, 2026 —
St. Louis Cardinals rookie JJ Wetherholt has been placed on the 10-day injured list. The move comes as a result of right wrist tendinitis, the team announced.
The exact date Wetherholt experienced the onset of symptoms or when the decision was made to place him on the injured list was not immediately detailed. His placement on the injured list means he will be sidelined for a minimum of 10 days, starting from the date of designation. The specifics regarding his potential return date beyond this initial period remain to be seen.
Tendinitis is an inflammation of a tendon, a thick fibrous cord that attaches muscle to bone. In Wetherholt’s case, the affected area is his right wrist. This condition can cause pain, tenderness, and swelling, and can affect an athlete’s ability to perform actions requiring grip strength, fine motor skills, or repetitive wrist movements.
As a rookie, Wetherholt’s development and contribution to the Cardinals’ season are often closely watched. Information regarding his previous injury history or any pre-existing conditions that might have contributed to this injury was not provided. The team has not released further details on the severity of the tendinitis or the expected rehabilitation timeline beyond the initial 10-day period.
The St. Louis Cardinals organization will likely provide updates on Wetherholt’s condition as more information becomes available or as he progresses through his recovery process. His absence will create a space on the active roster that the team will need to fill, potentially through a call-up from their minor league system or other roster adjustments.
