Tua Tagovailoa was forced out by a rib injury. Carson Wentz hurt his right ankle. Andy Dalton had a knee issue, and Tyrod Taylor exited with a hamstring injury.

It was a rough Sunday for quarterbacks.

Tagovailoa was knocked out of Miami's 35-0 loss to Buffalo when he was hit by A.J. Epenesa on a failed fourth-down play near midfield in the first quarter. Tagovailoa struggled just to get to the sideline and was carted to the locker room not long afterward.

Tagovailoa was having tests performed, a process that will continue into Monday, Dolphins coach Brian Flores said.

Pittsburgh outside linebacker T.J. Watt, Denver linebacker Bradley Chubb and Philadelphia defensive end Brandon Graham also were among the NFL's most notable injuries in Week 2.
