The Browns beat Pittsburgh 21-7 for only their fourth win of the season - ending the Steelers' four-game winning streak.
Garrett did not release a statement, but he posted a meme on his Twitter account of a scene from the film "John Wick" with the subtitle: "But now yeah, I'M THINKING I'M BACK!"
Garrett ripped off Rudolph's helmet and as offensive lineman David DeCastro pushed Garrett away, Rudolph pursued the 2017 No. 1 draft pick. Rudolph tried to pull off Garrett's helmet but couldn't. Maurkice Pouncey punched and kicked Garrett, earning a two-game suspension, while Cleveland's Larry Ogunjobi was suspended for a game for shoving Rudolph to the ground from behind. Rudolph wasn't suspended, but he was hit with a $50,000 fine for the altercation.
Garrett met with the league on Monday after missing the final six games of the Browns' season for the "Thursday Night Football" incident that shook the league and became national news for weeks.
Garrett, 23, had apologised for his "selfish and unacceptable" actions. "I know that we are all responsible for our actions and I can only prove my true character through my actions moving forward".
Garrett will be returning to a team that finished 6-10 and cleaned house, including the firing of head coach Freddie Kitchens after one season.
