Zach Collins, the center for the San Antonio Spurs, has been placed in concussion protocol after experiencing symptoms following a head injury during Sunday’s game against the Nets. As a result, he will miss the upcoming game against the Mavericks and will need to pass tests before returning to action.

The team has recalled Dominck Barlow from the G League, and this situation could mean increased playing time for Sandro Mamukelashvili, who has shown his hustle in limited appearances this season.

This injury adds to Collins’ already challenging season, having missed games earlier due to knee and ankle injuries. It’s another setback for the player.
