The chances of San Antonio Spurs forward Tim Duncan playing against the Los Angeles Lakers on Friday night don't look good.

Team officials said Thursday that Duncan is doubtful after he suffered a chest contusion in the third quarter in the team's opener against the Memphis Grizzlies on Wednesday night.

Duncan did not return and finished the game with three points and six rebounds in 17 minutes.

He did board the team charter plane Thursday afternoon for the three-game road trip.
