Springbok and Ulster loose forward Marcell Coetzee faces an anxious wait on the extent of his latest knee injury.
Coetzee was injured in the first half of Ulster' 19-13 PRO14 win over Glasgow on Friday. He played on but was substituted at half-time.
The 29-year-old was set to undergo scans to determine the extent of the knee damage.
Coetzee, who has played 30 Tests for the Springboks between 2012 and 2019, is set to leave Ulster to join the Bulls in July.
Coetzee had a nightmare run of recurring knee injuries in his first two seasons at the Irish club.
"We won't know how serious that is until we get a good look at it," Ulster head coach Dan McFarland said in his post-match interview.
