Paul was disagnosed with a Grade-2 hamstring strain.
After undergoing an MRI on Friday, Rockets general manager Daryl Morey said that Paul has been diagnosed with a Grade-2 left hamstring strain. No timeline has been set for Paul's return aside from a date for his reevaluation.
Paul, 33, had four points in 12 minutes during Thursday's loss. He left the game with 6:43 remaining in the second quarter after he appeared to grab his hamstring while attempting to take the ball away from Miami's Derrick Jones Jr.
Paul left the game for the locker room immediately after. The Rockets were outscored by 13 points after he exited in the second quarter.
The nine-time NBA All-Star has missed time due to hamstring injuries on five occasions during his career for a total of 19 games, including the playoffs, according to ESPN Stats and Information.
Houston is 0–5 in games without Paul this season. They are 16–15 on the season after Thursday's loss. The Rockets return to action against San Antonio on Sunday, Dec. 23. Tip-off is set for 8 p.m. ET.
