Carlson was removed from Monday's exhibition game versus the Cubs following a collision in the outfield with Jordan Walker, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Carlson had his legs taken out from under him by Walker and appeared to land awkwardly on his left arm. He then walked off the field with a trainer and is surely headed for testing. Carlson had been slated to be the Cardinals' center fielder while Tommy Edman (wrist) is out, but Carlson's injury could throw a wrench into those plans. It's possible that prospect Victor Scott could re-enter the mix for starts in center field if Carlson isn't ready to go for Thursday's season opener versus the Dodgers.
