The Carolina Panthers lost at home to the Philadelphia Eagles in a key Thursday night matchup, as they fell to 4-2 and may lose their division lead. To make matters worse, star middle linebacker Luke Kuechly had to leave the game with an injury. In other news involving linebackers, the Los Angeles Rams and Alec Ogletree have agreed to a massive contract extension. This deal comes as he was set to become a free agent.

Kuechly suffers concussion in loss

Towards the end of the second quarter, Carolina Panthers linebacker Luke Kuechly left the game after colliding with Eagles guard Brandon Brooks in the backfield on a goalline run.

He was then evaluated for a concussion, with it later being announced that he would not return. Kuechly will now be put into the concussion protocol.

This is the third time the star linebacker has suffered a concussion in the last three seasons. He suffered his first in the season opener of 2015, missing four games. The second came in week 11 last season and he sat out the rest of the year even after being cleared since the Panthers were not in contention.

Since being selected in the first-round in the 2013 draft, Kuechly has been a star and started all 77 games he had played in. According to Pro Football Reference, he has amassed 768 total tackles, nine sacks, 13 interceptions, five forced fumbles, five fumble recoveries, defended 47 passes and a defensive touchdown.

Kueckly won Defensive Rookie of the Year in 2012 and followed it up by winning Defensive Player of the Year in 2013.
