De'Aaron Fox will be sidelined for at least two weeks due to a partial tear in his right quadriceps muscle.

The tear was revealed in an MRI conducted Friday afternoon following the team's practice at Kaiser Permanente in Sacramento. Fox will be reevaluated in two weeks.

Fox, who turned 20-years-old last Wednesday, was seen riding a stationary bike during Friday's practice session at Golden 1 Center. Coach Dave Joerger ruled him out for Saturday's home game against San Antonio when meeting with the media and said he did not participate in practice.

The injury, originally diagnosed as a right quadriceps contusion, occurred during last Thursday's loss to the Timberwolves in Minnesota, when he collided with Karl-Anthony Towns in the first quarter. Fox did not return after halftime.

The following night, Fox missed the next contest in Toronto. He attempted to play two nights later in Philadelphia, but was pulled just 11 minutes into the game. He did not play the next night in the victory over Brooklyn to conclude the four-game road trip.

Fox in his first NBA season with Sacramento averaging 9.4 points and 3.7 assists through 29 games.
