Raiders Linebacker Suffers Concussion In Sunday's Game

They just can't catch a break.

Las Vegas Raiders linebacker Darien Butler left Week 17's game against the San Francisco 49ers with a concussion and did not return.

The Raiders continue to lose linebacker after linebacker to injury.

There's a good chance the former undrafted free agent's season is over if he cannot clear league protocols in time for Week 18's game against the Kansas City Chiefs.

In 15 games this season, the twenty-two-year-old has 11 total tackles.
