Rangers goalkeeper appeared to wrestle Celtic player to the floor.
Following a frenetic game at Celtic Park, the action did not stop at the final whistle.
Scott Brown was at the thick of it, involved in a clash with Rangers star Andy Halliday.
Halliday had taken exception to Brown taunting the Rangers supporters.
As stewards and officials came to separate the players, Rangers back up goalkeeper Wes Foderingham also got in on the act.
He appeared to wrestle Celtic’s Mikael Lustig to the floor.
Rangers fans gave Foderingham their backing.
The substitute goalkeeper has not had much to do this season, with Allan McGregor taking his place.
When he has been called upon, he stepped up.
His actions at the final whistle were not believed to be dealt with at the final whistle, and it remains to be seen if they will be addressed by the SFA compliance officer.
In the mean time he appears to have endeared himself to Rangers supporters.
