Glen Davis is questionable to play in Saturday’s Game 7 of the Clippers’ first-round series against the Spurs, a potentially huge blow to coach Doc Rivers’ eight-man rotation. Davis will be a game-time decision after spraining his left ankle with 11:07 left the Clippers’ 102-96 Game 6 victory in San Antonio Thursday night.

“We’ll find out more (Saturday),” Rivers said on a conference call. “We won’t know much (Friday).”

Davis is just one of eight Clippers to have played in all six games of the series. He was helped off the court by the training staff, ruled out for the rest of the game and taken to the locker room in a wheelchair Thursday night.

Hedo Turkoglu and Spencer Hawes are the primary candidates Rivers mentioned to fill Davis’ 6-foot-9, 289-pound void, but the two have played a combined 33 minutes in the series. Or the Clippers could opt for a smaller lineup.

“We got Turk. We got Spencer,” Rivers said. “We can go small. We basically did that last night. The game will dictate that.”

Davis, Jamal Crawford and his son Austin Rivers are the only three reserves Doc Rivers has trusted to consistently come off the bench in the postseason. Davis is averaging 3.2 points and 2.8 rebounds in 12.3 minutes per game in addition to contributing an important emotional component, according to Chris Paul.

“I don’t know how serious it is,” Paul said Thursday night of Davis’ sprained ankle. “I know Big Baby’s a worker. Guys stepped up when he went down, but we need him. Baby’s an emotional leader for our team. He really leads that second unit.”
