LOS ANGELES (AP) -- Carson Wentz threw for 291 yards and four touchdowns before leaving with a knee injury and Jake Elliott kicked the go-ahead 33-yard field goal with 3:45 left for the Philadelphia Eagles, who beat the Los Angeles Rams 43-35 in a thriller Sunday to clinch the NFC East title.
Two sources familiar with the injury tell The Associated Press that doctors believe Wentz has torn his left anterior cruciate ligament and will miss the rest of the season and playoffs.
Wentz needs an MRI to confirm the severity of the injury. Both people spoke to the AP on condition of anonymity because they weren't authorized to release the information.
Wentz was hit hard as he scrambled into the end zone on a play that was called back because of holding. He stayed in the game and threw a 3-yard touchdown pass to Alshon Jeffery four plays later to give the Eagles the lead.
Foles replaced Wentz on the next drive for Philadelphia (11-2).
The NFC West-leading Rams (9-4) then went up 35-31 on Todd Gurley's second short TD run.
Elliott kicked a 41-yard field goal to pull the Eagles to 35-34. His go-ahead field goal was set up when Chris Long, a second-round draft pick of the then-St. Louis Rams in 2008, had a strip-sack of Jared Goff, with Rodney McLeod recovering.
Elliott kicked a 54-yarder, but the Eagles got an automatic first down on a personal foul on Aaron Donald. Elliott kicked the winner four plays later.
The game ended on a crazy play, when Philadelphia's Brandon Graham grabbed a lateral by Tavon Austin out of the air on the game's last play and scored what was ruled a 16-yard fumble return.
The Eagles clinched their first division title since 2013.
This was the eighth time in the Super Bowl era that quarterbacks taken No. 1 and No. 2 overall in the same draft squared off. Goff was the first pick overall in 2016, followed by Wentz.
Goff threw for 199 yards and two touchdowns.
