During the Oakland Raiders' Week 7 game against the Kansas City Chiefs, Marshawn Lynch ran onto the field and made contact with an official, causing him to be ejected from the game. The Raiders were able to win the game 31-30 without him.

The running back was issued with a one-game suspension by the NFL, meaning he will miss Oakland's trip to Ralph Wilson Stadium in New York to take on the Buffalo Bills this weekend in their Week 8 game.

Despite missing the game, however, Lynch is making sure he keeps himself in tip-top condition for his team's Week 9 game against the Miami Dolphins by practicing against an unlikely opponent, his old high school football team.

BeastMode kept busy during his one-game suspension by spending some time practicing this week with the football team at his alma mater, Oakland Technical High School, even though the school committed a rules violation by allowing Oakland Raiders running back to practice with them.

Despite the fact he was playing against high school students, Lynch wasn't taking it easy on them, as you can see in the video further down, as he delivered a vicious stiff arm at one point as well as forcing six players to bring him down.

Raiders offensive coordinator Todd Downing didn't comment on Lynch training with high schoolers. Instead, he kept his focus on his team's game against the Bills this weekend.

He said, according to ESPN: "To be honest with you, I'm so focused on this situational Thursday. We have third down, red zone, all of that going in today. I was dialed in on Buffalo.

"I don't really know what it was. I know that he loves football and he's a football junkie. I wouldn't expect anything different. We're excited to go put on a good showing with Buffalo and meet up with him after that."

Even though he looked great in the video above, Lynch has been a shadow of his former self for the Raiders this season, as he has only rushed for 266 yards and two touchdowns on 72 carries so far, achieving a career-low 3.7 yards per rush.
