Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
But he picked up a tournament-ending hernia injury and was ruled out of the rest of the tournament in the Georgian capital, with Munster's David O'Callaghan called up in his place.
The 29-year-old Stevenson, who played 19 times for Ulster this past season, is expected to be out of action for six to eight weeks following the operation.
Meanwhile, Ulster Rugby are serving up some special present ideas in time for Father's Day this coming Sunday.
