Stuart Olding will switch to full-back for Ulster’s clash with Glasgow Warriors on Friday night and the 22-year-old is itching to make up for lost time.

Rising star Olding, who has only just returned to action following a ten month injury lay-off, passed initial concussion tests after taking a heavy blow in a collision with Carl Meyer in last week’s clash against the Dragons.

But he insists he has no concerns about his fitness to feature against the Warriors at Kingspan Stadium.

“I’ve had plenty of time out and I’ve come back a better player,” said Olding.

“You learn a lot about yourself when you are on the sidelines but I’ve missed too much rugby to miss anymore.

“I’ve had no issues since that collision, no headache or anything. I’ve passed all the concussion protocols and I’m feeling confident that I’ll be there for selection.”

Sam Windsor will make his Ulster debut in the crucial fly-half berth in Friday's GUINNESS PRO12 game against Glasgow as Paddy Jackson is named on the bench.

Windsor, 28, starts as Ian Humphreys is ruled out but Stuart McCloskey, Franco van der Merwe and Nick Williams are drafted in.

For the Warriors Gregor Hunter will make his first start despite having signed for the club in the summer of 2014.

Following an ACL injury, he recovered to go on and win the Melrose 7s last year, as well as making his Warriors debut coming off the bench against Munster earlier this season.

Peter Murchie starts at full-back, while Rory Hughes starts on the left wing following his try against Ospreys. On the opposite wing is Lee Jones.

Glenn Bryce and Sam Johnson start at centre, with Johnson starting his fourth consecutive game. Hunter and Ali Price make up the half-back pairing.

In the front row, Ryan Grant, Pat MacArthur and Sila Puafisi will pack down.

Greg Peterson and Leone Nakarawa pair up in the second row with No.8 Ryan Wilson captaining the team for the second game in a row. Simone Favaro and Rob Harley are the named flankers.

Head coach Gregor Townsend said: "We're heading to the Kingspan Stadium expecting a tough match against one of the strongest teams in the league, who are currently top of the GUINNESS PRO12.

"We played well in Wales against Ospreys for around 60-65 minutes, but we'll need an 80 minute performance tomorrow night to come away with a positive result. I'm looking forward to seeing this group of players front up in what is a big game for the club.

"Gregor Hunter has worked really hard in training this season and has been playing regularly for Glasgow Hawks, so we're expecting him to play well in a Warriors shirt tomorrow night."
