Samoa wing David Lemi will make his debut for Glasgow Warriors in Friday's RaboDirect PRO12 clash with Ulster at Firhill.
Former Bristol and Wasps wing Lemi, who was a member of Samoa's World Cup squad and signed earlier this month, is included as one of six changes as Glasgow's focus returns to the Celtic League following two Heineken Cup encounters.
Head coach Sean Lineen told www.glasgowwarriors.org: "David Lemi has already made clear his class in training, and he's the sort of player our fans will really take to."
Federico Aramburu returns on the wing, with Troy Nathan at outside centre and Henry Pyrgos poised to start at scrum-half, while in the forwards, Jon Welsh is set to begin at loosehead prop, with Tom Ryder starting at lock.
The Warriors are seeking to return to winning ways after the loss at Leinster last Sunday, which ended a five-match winning run.
Lineen added: "We were disappointed with the manner of our loss to Leinster, and as a group we've been working hard all week to address the areas where we didn't get it right.
"The players have shown great character and determination in the last couple of months, securing a number of excellent results in the process, and that's what we're looking for in spades come Friday night.
"Ulster are a tough proposition all over the field. We'll need to show real aggression in contact and appetite for the battle. The guys have delivered that many times already this season, so I've every confidence they'll put in a much improved performance."
Tighthead prop Moray Low is included among the replacements and is in line for a first Glasgow appearance of the season following his involvement in Scotland's World Cup squad and a calf injury.
Scrum-half Chris Cusiter, who on Tuesday agreed a three-year contract extension, is alongside Low on the bench, with second row Richie Gray also named as a replacement.
