The Scottish Football Association have handed one-match bans to Celtic's Gary Caldwell and Rangers' David Weir following their part in the melee at the end of last night's fiery Old Firm derby.
Defenders Caldwell and Weir squared up to each other on the pitch after the final whistle at Parkhead, and the Scotland team-mates will now miss crucial games for their respective clubs.
Caldwell will be absent for Celtic's Clydesdale Bank Premier League game against Aberdeen on Saturday, and Weir must sit out Sunday's Scottish Cup semi-final against St Johnstone.
SFA disciplinary and referees chief Drew Herbertson said: 'It is the case that David Weir and Gary Caldwell are to be reported for violent conduct which means both will be suspended for the next match.'
Caldwell and Weir were summoned to referee Kenny Clark's room after the match which Celtic won 2-1 thanks to Jan Vennegoor of Hesselink's stoppage-time header.
The tempestuous clash had already seen one red card shown, when Weir's centre-back colleague Carlos Cuellar was sent off for handball on the line as he prevented Shunsuke Nakamura scoring a second Celtic goal.
Clark will also include details in his match report of the incident which saw Rangers doctor Paul Jackson struck by an item thrown from the crowd as he attended to injured goalkeeper Allan McGregor.
That issue will be addressed by the Scottish Premier League, rather than the SFA, once they receive Clark's report.
