Los Angeles Rams quarterback Jared Goff underwent surgery on his broken right thumb Monday in Los Angeles and won't play Sunday against the Arizona Cardinals, coach Sean McVay said on Monday.

"We felt like that was going to be the best thing to do for him and for our team," McVay said, adding that Goff had some screws inserted and that he could return for the playoffs if the Rams advance.

John Wolford is Goff's backup and will start in his place.

Goff injured his thumb in the final seconds of the third quarter Sunday in Seattle as he completed a 9-yard pass to tight end Gerald Everett. As he followed through on his throw, Goff's right hand hit the helmet of Seahawks defensive end Benson Mayowa.

"Popped it back into place," Goff said, "and just finished the game."

During his postgame videoconference with reporters, Goff downplayed the impact of the injury and said his thumb felt "not terrible."

He also said his thumb didn't bother him on throws, as Goff completed 6 of 14 passes for 74 yards after the injury.

The Rams' 20-9 loss to the Seahawks on Sunday marked the first time this season they have lost two straight games. They can still clinch a playoff spot with either a win against the Cardinals or a Green Bay Packers victory at the Chicago Bears in Week 17.
