Saracens head coach Mark McCall says a comment to hooker Jamie George by one of Munster's medics caused a brawl involving almost 30 players.
Assistant coach Alex Sanderson had told BT Sport during Saracens' 15-6 Champions Cup win that it was related to George's weight.
"As far as I know, one of their medical team said something which wasn't all that good," said McCall.
"Whether the fight helped, I don't know," added McCall, who will consider whether to raise the matter with Champions Cup organisers.
