San Antonio sixth man Manu Ginobili is considered doubtful for Monday's 7 p.m. contest against the Thunder at Chesapeake Energy Arena.
Ginobili suffered a bruised left quad in the first quarter of the Spurs' victory at home against Boston on Saturday night and did not return.
“He got a thigh contusion just above his knee and one would think he is going to be stiffer than hell (on Sunday),” Spurs coach Gregg Popovich told reporters. “It's hard to believe he'd be ready day after (Sunday) for Oklahoma, but I'm not sure.”
Ginobili also missed this season's previous meeting against OKC at the AT&T Center on Nov. 1, when San Antonio won 86-84 on Tony Parker's 20-foot buzzer-beater.
Spurs forward Stephen Jackson will miss Monday's game with a finger injury.
For the Thunder, rookie forward Perry Jones III continues to heal from an ankle injury.
INCIDENT ‘BEHIND US'
When Thunder forward Serge Ibaka and Los Angeles Lakers forward Metta World Peace became entangled on Dec. 7, Jackson sent a hostile tweet to Ibaka for which the NBA fined him $25,000. Jackson and the Spurs quickly apologized.
