Oakland Raiders running back Marshawn Lynch recently made a return to Oakland Tech, the place where he played his high school ball, and didn't hold back when going up against the current football team.

The bruising 215-pound running back shared a clip on instagram of his practice at Oakland Tech, which includes one devastating stiff arm to some poor teenager. It's unclear if the video was shot this week during his suspension or earlier this month, but that's neither here nor there. The bottom line is Marshawn returned to his HS to practice with the football team and it was awesome.

Check out the clip below.

The Raiders' 31-year old running back won't be eligible for this Sunday's matchup against the Buffalo Bills, due to an incident that took place during their game against the Kansas City Chiefs last Thursday.

During the second quarter of Oakland's thrilling 31-30 win over the division rival, Marshawn ran onto the field to break up a scuffle between the Raiders' offensive linemen and Chiefs cornerback Marcus Peters. Amid the altercation, Marshawn grabbed an official and was promptly ejected from the game.

The league suspended Lynch for his actions, and upheld the ruling after his appeal was heard earlier in the week.

According to ESPN, Lynch argued that other players have made contact with officials in the past and have not been suspended. Marcus Peters also spoke on Marshawn's behalf.

"Lynch had argued at Monday's appeal hearing that nine other players, including Aaron Donald and Taylor Lewan last season, have made contact with an official and none have been suspended, a source told ESPN's Adam Schefter."

"The source also said that Peters spoke on Lynch's behalf during the hearing, which was held by conference call."

"Peters told Thrash that Lynch was trying to calm him and the situation."

In seven games this season, Marshawn has rushed for just 266 yards and two touchdowns, while the Raiders have struggled with a 3-4 record.
