White Sox outfielder Charlie Tilson suffered a stress reaction in his right foot while going through drills Friday, the team announced Sunday.

Tilson will be held out of impact activities for 10 days and then re-evaluated. A stress reaction is less serious than a fracture, but it’s still a bad break for a player who was just returning from season-ending surgery last year.  

Tilson, a New Trier High School graduate, joined the Sox in the Zach Duke trade with the Cardinals at the trade deadline last season. The Sox called him up immediately to make his major-league debut in center field, but he tore his left hamstring while running to make a diving catch in the game against the Tigers at Comerica Park.

He rehabbed from the surgery and was hoping to work his way back to game speed early in spring training as he competed to be the Sox’s starting center fielder. Sox general manager Rick Hahn said the first day of camp that Tilson had the “inside track” for the job, if he was healthy.

“Assuming Charlie Tilson is 100 percent, we’d all like to see what he can do on a regular basis out in center,” Hahn said then.

The latest injury means Tilson won’t be ready to go by the time Cactus League play opens Saturday. After trading Adam Eaton to the Nationals in December, the Sox have openings for a center fielder and a right fielder.

With Tilson out, Peter Bourjos and Leury Garcia would be the two most likely options to spend time in center field. Sox prospects Adam Engel and Jacob May could also be used there, though Hahn has acknowledged that both could need more development time.
