Spurs forward Tim Duncan underwent a CT scan this morning in San Antonio which confirmed that he has a chest contusion, the team announced on Thursday.

He suffered the injury during the third quarter of last night's Spurs-Grizzlies game. His status is day-to-day and he is listed as doubtful for Friday night's Spurs-Lakers game.

Duncan will travel with the team this afternoon when the Spurs depart for a three-game trip that begins in Los Angeles.
