Though Chris Paul promises to be ready to play tomorrow night in Game 6, his injury and that of teammate Blake Griffin are causes for concern. From the OC Register: “Blake Griffin injured his left knee and Chris Paul strained his right hip flexor in the Clippers’ 92-80 loss to the Grizzlies on Wednesday at the FedEx Forum in Memphis. Both Griffin and Paul returned to the game but looked visibly uncomfortable. Griffin’s injury occurred when he drove the lane on Marc Gasol, drawing a foul before landing awkwardly on his left leg, which flexed backwards. The Clippers called the injury a hyperflexed knee before diagnosing it as a sprain. Paul, who missed the final game of the regular season, was noticeably bothered by the injury. Griffin will have an MRI on the knee Thursday in Los Angeles. ‘The pain scares you most,’ he said. ‘It’s not because it hurts; it’s because you don’t know why.’ Griffin said the knee stiffened up on the court after he returned, but the pain felt different than the left patella fracture that kept him out for his rookie season. Paul vowed to be on the court Friday for Game 6. ‘I’ll be ready,’ he said, adding that both he and Griffin are ‘tough guys.’”
