The NFL announced the fines Friday.
Oher's fine stems from punching Browns defensive end Robaire Smith. Oher hit Smith after Smith shoved Baltimore tight end Todd Heap following a whistle that had stopped play for a false start.
Oher says he was defending his teammate and will not appeal the fine.
Zbikowski tackled Browns running back Peyton Hillis out of bounds at the end of a 48-yard run. The play drew a penalty for unnecessary roughness.
