Browns safety Ronnie Harrison was fined $12,128 by the league for his unsportsmanlike conduct penalty on Sunday stemming from an incident along the Chiefs sideline in the first quarter of the Browns’ 33-29 loss at Arrowhead Stadium, a league source told cleveland.com.

Harrison was ejected from the game after shoving Chiefs running backs coach Greg Lewis.

Lewis was not fined. NFL Network’s Tom Pelissero reported he received a warning that any subsequent violations will result in discipline.

The incident happened early during Sunday’s loss at Arrowhead Stadium, just five plays into the Chiefs’ first drive.

Harrison and linebacker Mack Wilson tackled Chiefs running back Clyde Edwards-Helaire along the Chiefs sideline. While Edwards-Helaire was on the ground, Harrison was bumped by Chiefs offensive lineman Creed Humphrey, causing him to step on Edwards-Helaire. Lewis pushed Harrison off the running back and Harrison responded by shoving Lewis.

Harrison was replaced in the game by M.J. Stewart.

Browns head coach Kevin Stefanski, who wouldn’t disclose if there was any internal discipline for Harrison, said on Friday a memo was sent by the league regarding the incident.
