A major hit to the Browns defense took place during Sunday’s game against Detroit when linebacker Jamie Collins suffered a knee injury following his interception of Lions quarterback Matthew Stafford.

On Monday afternoon, head coach Hue Jackson confirmed that Collins would be done for the season with an MCL injury.

“That’s a big blow to our defensive football team,” Jackson told reporters in his weekly Monday press conference.

This puts to an end to a tough 2017 season for Collins who’s dealt with injuries throughout the season. He missed three games earlier this season with a concussion he suffered during the Week 2 matchup against Baltimore.

In six games this season, Collins has made 31 tackles (21 solo), 1 sack, 1 forced fumble and the interception he got during Sunday’s game.

This comes after signing a four year, $50 million dollar contract with the Browns during the offseason which guaranteed him his first two seasons of salary at $26.4 million when he signed the deal.

The team acquired him from New England at the trade deadline last season for a third round pick and Collins performed well in 8 games with 69 tackles (48 solo), two sacks and a forced fumble.

He can opt out of the deal following the end of the 2018 season but with an injury like this, he may stick around for the final two seasons and collect the remaining $23.6 million because he may not see another contract like that despite becoming a free agent again at 31 years old in 2021.

Replacing Collins in the lineup would be James Burgess who’s had some flashes when filling in for him earlier in the season. In seven games this season, the 23 year old rookie has 23 tackles (16 solo), two sacks and a forced fumble.
