LOS ANGELES — The thousands of Philadelphia Eagles fans that annexed Los Angeles Memorial Coliseum on Sunday, that turned the seating bowl into a green-and-white party before, during and after their team’s absurd victory over the Rams in one of the more absurd N.F.L. games this year, could tell their friends they were there when Carson Wentz threw four touchdown passes to set the franchise’s season record.

They could say that they watched their team clinch the N.F.C. East, outlasting the formidable Rams by 43-35. They could say they watched the Eagles reach 11-2, best in the N.F.L., and reclaim the No. 1 seed in the rugged N.F.C., enhancing their chances of a first-round bye.

They could say all that, but when they glance at their ticket stubs, they will not.

Because late in the third quarter Sunday, Wentz absorbed hits from both sides as he dived headfirst toward the end zone, and the collisions contorted his left knee in an odd way, and even though he stayed in four more plays to guide Philadelphia to a touchdown, he hobbled toward the tunnel with a towel over his head — a sight about as soothing as Ronde Barber’s ruining the Eagles’ finale at the old Veterans Stadium with an interception for Tampa Bay in the 2002 N.F.C. Championship Game.

That Eagles team was supposed to reach the Super Bowl, and maybe, just maybe, this one was, too. The Eagles have balance and depth and resilience and swagger. They had Wentz, and now they will not.
