San Antonio Spurs forward Tim Duncan is doubtful for Friday's game against the Los Angeles Lakers due to a chest contusion.
Duncan, injured in Wednesday's season opener against the Memphis Grizzlies after taking an inadvertent elbow in the third quarter, underwent a CT scan Thursday morning in San Antonio that confirmed the chest contusion.
Duncan, listed as day to day, will travel with the Spurs on their upcoming three-game road trip.
