Los Angeles Rams QB Jared Goff has thumb surgery; unlikely to play Sunday vs. Arizona Cardinals

Los Angeles Rams quarterback Jared Goff underwent surgery on his broken right thumb Monday in Los Angeles and is unlikely to play Sunday against the Arizona Cardinals, sources told ESPN's Adam Schefter.

If he can't play Sunday, Goff could return for the playoffs if the Rams advance.

John Wolford is Goff's backup and in line to start.

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.
