Westbrook, who departed midway through the second quarter after fracturing his right hand, was walking to the locker room but stopped suddenly near the tunnel in reaction to something said by a fan sitting near the tunnel entrance.
It's unclear what the fan said to provoke Westbrook, but the player responded by saying, "Watch your mouth." He pushed away security personnel trying to usher him to the Thunder locker room, even using his injured hand to do so. After a few more seconds, Westbrook continued walking to the locker room.
Video of the incident, from TNT's broadcast:
And video shot by another fan (warning: explicit language):
Westbrook appeared to injure his hand by accidentally hitting it on the back of Thunder center Kendrick Perkins while going for an offensive rebound in traffic. He later returned to the team's bench but didn't play, instead sitting with his hand wrapped in ice.
It was reported Friday that Westbrook could miss four to six weeks due to the injury.
Oklahoma City is already without star forward Kevin Durant for likely another month after having surgery to repair a Jones fracture in his right foot. Backup point guard Reggie Jackson has missed the team's first two games with an ankle injury but could return as soon as Saturday. Jeremy Lamb, Mitch McGary, Anthony Morrow and Grant Jerrett are also injured.
Westbrook stayed healthy through the beginning of his NBA career before tearing his meniscus in the 2013 playoffs, which limited him to 46 games last season after several subsequent surgeries.
The point guard had two points and four assists against the Clippers before leaving with his injury. He led the Thunder with 38 points in their season-opening loss to the Portland Trail Blazers on Wednesday.
Oklahoma City next plays the Denver Nuggets on Saturday.
