It looks like fireworks have already started between the 49ers and Browns.
Minutes before the start of the game, the video showed the entire teams coming together for a scuffle on the sidelines as coaches moved in to separate everybody.
The 49ers come into this game with a 5-0 record while the Browns are 2-2 and looking to avoid going under .500. It will be a tough task as the team will once again be without quarterback Deshaun Watson.
The Browns may be trying to send a message that this game will not come easy for the Niners.
