The San Antonio Spurs' quest to get back to the NBA Finals is off to a rough start.
The team announced on Thursday that forward Tim Duncan is day-to-day and listed as doubtful for Friday's game against the Lakers.
The Spurs say Duncan underwent a CT scan which confirmed he had a chest contusion.
Duncan suffered the injury in the third quarter of the Spurs' season-opening win over the Memphis Grizzlies on Wednesday.
He will travel with the team on their three-game road trip to the west coast.
Duncan is entering his 17th season in the NBA and had one of his best years in nearly a decade last season.
He played in 69 regular season games in 2012-13, averaging 17.8 points and 9.9 rebounds in the Spurs' run to the NBA Finals.
