The Blazers proved to be no match for coach Marc Daignault's team, as the Thunder held on for a 128–120 victory.
However, the game took a dramatic turn during the second quarter when Biyombo experienced a concerning moment.
Early in the timeout, Biyombo took an unexpected tumble and crashed along the Thunder sideline. After briefly lying on the floor, he was helped back to the locker room.
Although team officials brought out a wheelchair for the 31-year-old 6-foot-8, 255-pound center, he was able to walk to the locker room without needing one.
Following an evaluation, the Thunder confirmed that the 13-year veteran is in good health and has not suffered any serious medical issues.
Coach Digneault later mentioned that Biyombo was in good spirits, joking and laughing in the locker room at halftime.
The game was only Biyombo's fifth appearance with the Thunder since he joined the team on Feb. 10. His availability is uncertain for Friday's game against the Miami Heat.
