Munster's Tadhg Beirne and Andrew Conway are on course to face Ulster in Friday night's URC quarter-final clash at Kingspan Stadium.
Beirne has been out since the Six Nations with a thigh injury but are now close to a timely return with the Reds' season on the line in Belfast, while Conway aggravated a knee issue in the province's disappointing final regular round defeat to Leinster.
"We just got off the training park just now and they completed the full session, so that was a positive step for them," said Munster's senior coach Stephen Larkham.
