Wide receiver Cooper Kupp has suffered a season-ending knee injury, head coach Sean McVay confirmed on Monday morning.

Kupp went down with the non-contact injury on a deep route early in the fourth quarter of Sunday's 36-31 victory over the Seahawks. He was able to walk off the field, but with heavy trainer assistance.

A second-year receiver out of Eastern Washington, Kupp has been a heavy contributor to the Rams' offense since he was selected in the third round of last year's draft. He set a franchise rookie record with 62 receptions in 2017, also leading the team with 869 yards receiving.

This season, Kupp played an even heavier role in the offense with Los Angeles utilizing almost exclusively three wide receiver sets. He put up a career high nine receptions for 162 yards and two touchdowns in the Week 4 victory over the Vikings.

But injuries also plagued Kupp this season. He suffered a concussion during Los Angeles' Week 5 victory over Seattle. After recovering from that, he suffered a knee injury against Denver the following week. Kupp missed the Week 7 and Week 8 victories over San Francisco and Green Bay, respectively, before coming back to play in New Orleans in Week 9. He made five receptions for 89 yards with a touchdown in that contest.

Kupp's 2018 will end after a day where he reached 100 receptions in his young career. Kupp will finish the season with 40 receptions for 566 yards. He also currently leads the team with six touchdown receptions.
