Scotland flanker John Barclay has shaken off a stomach bug to make the starting line-up for Glasgow Warriors clash against Ulster on Friday.
Barclay withdrew from the side during the warm-up prior to the 27-19 victory over the Dragons two weeks ago, but will return to complete the Killer B's back-row for Friday night's Magners League encounter.
And ahead of the second of three home matches in an action-packed April for the Firhill side, head coach Sean Lineen was quick to praise the swift return of his all-action star.
"John gave his absolute all against Munster where he was absolutely outstanding," he said.
"I haven't seen a performance like that from a seven in a long time. However, we need the back-row to step up as a group and the front five have a huge job to do in order to give us the platform for success.
"Every game is a knock-out game, so this Friday is massive for us.
"Ulster have won on their last three visits to Firhill and they always get a good following here in Glasgow.
"But our support has been fantastic all season and I've no doubt that the Glasgow fans will make the most noise and really get behind the players."
Wales' acting head coach Rob Howley has given Sam Davies and Rory Thornton a boost ahead of the RBS 6 Nations by naming the uncapped Ospreys duo in his largely experienced squad for the Autumn Internationals.
