Los Angeles Chargers star Khalil Mack suffered a gruesome arm injury early in the team’s game against the Las Vegas Raiders on Monday night.
Mack and his teammate Troy Dye were chasing down Raiders wide receiver Tre Tucker toward the end of the first quarter. Mack’s left arm appeared to get jammed underneath Dye as they both went for the ball carrier.

The star pass-rusher immediately came out of the game as the quarter came to a close. The Chargers said initially that Mack was questionable to return due to an elbow injury, but was downgarded to out after he was seen on the sideline with his pads off and his arm in a sling.

The Chargers were a top defense last season, finishing first in points allowed and 11th in yards allowed on their way to an 11-6 record and a wildcard berth.

It would be a huge blow for the Chargers’ defense should the team lose Mack for a significant amount of time. Chargers head coach Jim Harbaugh said Mack will undergo imaging tests.
The Chargers won the game, 20-9.
The linebacker earned the ninth Pro Bowl selection of his career last season with the Chargers and his fourth consecutive nod. He played in 16 games, recording six sacks and 39 tackles. He had nine pass breakups and two forced fumbles as well.
Bud Dupree and Kyle Kennard were listed as Mack’s backups on the Chargers’ depth charts.
