In the second quarter of the Thunder's 114-96 victory over Phoenix on Monday night, Suns forward Luis Scola inadvertently elbowed OKC All-Star point guard Russell Westbrook above the right eye.
A bloodied Westbrook remained underneath the Thunder's basket and went to the locker room at the next stoppage of play with 1:13 remaining.
Second-year guard Reggie Jackson started the second half in place of Westbrook and the Thunder opened the third quarter with a 12-0 run to take a 66-53 lead.
Jackson finished with six points (3 for 3 from the field), six assists and four rebounds in 15 minutes.
Westbrook received stitches and did not emerge from the locker room until the 7:05 mark of the third quarter. He immediately went to the scorer's table and checked in at 6:24 with OKC ahead 68-59.
Westbrook has not missed a game in his NBA career (342 games), the league's longest active streak. He finished with 24 points, nine assists, seven rebounds and just one turnover in 33 minutes.
