It appears Morrison damaged medial ligament in his knee – an injury that can keep a player sidelined for months – but Glasgow coach Sean Lineen was optimistic he will be back in action before the RBS 6 Nations kicks off.
He said: “He has a knee injury and won't be out for that long but we don't know how long yet.
“He's a key man for us and him going off meant we had to realign ourselves.
“There are a few battered bodies in there - it was a tough old encounter. It was a real full-blooded game - a typical derby match with no love lost.”
The no love lost extended to Scotland lock Scott MacLeod and Chris Fusaro receiving red cards in an ill-tempered affair for their part in an all-out brawl.
The damage did not end there with impressive lock Richie Gray also picking up a knee injury which leaves him doubtful for the return match at Murrayfield although that is not thought to threaten his participation in the Six Nations.
