Shai Gilgeous-Alexander high-fiving Bismack Biyombo
Fans are praying for Oklahoma City Thunder center Bismack Biyombo following his scary collapse during a game against the Portland Trail Blazers on Wednesday night.

In what was a brief but worrying episode, the Congolese big man suddenly fell to the floor while high-fiving teammates on the sideline after a stoppage.

Biyombo had just high-fived Shai Gilgeous-Alexander when he collapsed on his back. Shai, who has taken much criticism for treating the incident with indifference, continued walking to the bench and sat down while other teammates gathered around the 14-year veteran.

Fans were pretty worried after catching the clip online, and the reactions came in plentitude

Fortunately, the center was able to walk off the floor on his own and was cleared of any serious medical conditions by Blazers doctors on site. Still, he was ruled out for the remainder of the game for precautionary reasons.

Per reports, the 31-year-old did not suffer a severe medical incident but such a collapse will rule him out until he and the Thunder can determine exactly what caused it.
