Four starting quarterbacks were forced out of games on an injury-riddled Sunday afternoon in the NFL.

The Miami Dolphins' Tua Tagovailoa was carted off with a rib injury in the first quarter of Miami's 35-0 loss to the Buffalo Bills, while the Houston Texans' Tyrod Taylor left with a hamstring injury after securing a 14-7 lead over the Cleveland Browns with a 15-yard scramble to the end zone in the second quarter. The Browns rallied to win 31-21.

"They are getting tests done on Tua," Dolphins coach Brian Flores said. "We don't know the severity of the injury right now,"
