Paul left Saturday's Game 7 victory over the San Antonio Spurs late in the first quarter with a hamstring strain and returned midway through the second quarter. Rivers told reporters after the game that he is "very" concerned about Paul's health and "guesses" he won't play in Game 1.
Sunday, the Clippers listed Paul as questionable for the game.
Though Paul returned to Saturday's game, he was seen limping at times and grimacing on the bench. Despite the injury, he scored the game-winning basket on a layup with one second left and finished with 27 points on 9-of-13 shooting.
Paul played in all 82 games this season for the first time in his career. He averaged 19.1 points per game and led the league with 10.2 assists per game.
The Clippers-Rockets series will begin Monday in Houston.
