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.
