TCU beat the No. 18 Sooners 55-24.
With Oklahoma trailing 34-10, Gabriel ran around the left end, slid feet-first and was hit hard by TCU linebacker Jamoi Hodge, who lowered a shoulder into Gabriel’s helmet. Gabriel laid on the turf for several minutes as players on both teams had to be separated.
Hodge was flagged for targeting and ejected.
Gabriel, who was 7 of 16 for 12 yards before the injury, walked off the field with help and was later ruled out for the rest of the game. Gabriel was replaced by Davis Beville, a 6-foot-6, 235-pound junior who transferred from Pitt this offseason.
Two plays later, the Sooners scored on a 20-yard run by Jovantae Barnes to cut the lead to 34-17.
Beville finished 7 of 16 for 50 yards.
