Rockets forward Trevor Ariza will undergo tests on Monday to determine the extent of his hamstring injury after he left Sunday's game in the first minute.
The Rockets have considerably less concern about Chris Paul, who played just 88 seconds in the fourth quarter before he was pulled, but insisted he was "fine" after the Rockets 113-102 win against the Suns on Sunday.
Ariza drove for a dunk attempt, drawing a foul from the Suns' Marquese Chriss. Ariza needed several minutes to gather himself, bending over to try to loosen his left hamstring. He stayed in to take his free throws, but six seconds later, took an intentional foul and immediately walked to the locker room.
