The team announced Tuesday that Cousins underwent an MRI on Tuesday that confirmed he had suffered a torn left quadriceps muscle. He is to begin rehabilitation immediately.
Cousins suffered the quad injury with 8:09 to play in the first quarter of Monday’s 135-131 Game 2 loss to the Los Angeles Clippers.
He was going for a loose ball and did not make contact with another player when the injury took place.
Cousins stayed down for a few moments and then waived down the training staff. He eventually made his way to the locker room, walking gingerly on his left leg.
The center suffered a torn Achilles tendon last season with the New Orleans Pelicans, which forced him to miss almost a year of action.
He signed a one-year deal this off-season with the Warriors, playing in 30 games, averaging 16.3 points per game with 8.2 rebounds in just over 25 minutes.
