New York Yankees second baseman Jazz Chisholm Jr. leaves a game early after colliding with teammate Jasson Domínguez during play, and is subsequently placed in concussion protocol. Multiple outlets report that the incident occurs as Domínguez and Chisholm both pursue a ball, with Chisholm remaining down for a period before being helped off the field at Yankee Stadium. Yahoo Sports and The Athletic describe the collision as a “scary” moment and note that Chisholm exits the game shortly afterward. The concussion protocol placement is consistently reported across sources, indicating the Yankees treat the incident as a head-injury concern pending further evaluation. The reports also frame it as part of a recent stretch of issues for Chisholm, including prior events in the same week noted by Yahoo Sports. Separate reporting includes mention of another injury scare from an earlier matchup, but the shared core of this story is the collision with Domínguez, Chisholm’s early exit, and the subsequent concussion-protocol status. The Yankees have not provided additional confirmed details beyond the protocol information in the cited accounts.
