On the other hand, the visitors have been massively lifted by the timely returns of both Jacob Stockdale and Louis Ludik, who slot straight into the back three as their side look to reach the final for the first time in six years.
Glasgow start the game with a front-three of Jamie Bhatti, Fraser Brown and Zander Fagerson, with Scott Cummings and Jonny Gray behind them on in the second-row.
The pack is finished with the strong trio of Rob Harly, Gibbins and Matt Fagerson
Scotland international Ali Price opens at scrum-half with Adam Hastings partnering him from fly-half. Sam Johnson and Kyle Steyn are just outside the pair in the 12 and 13 jerseys respectively.
It is a formidable back-three as van der Merwe and Tommy Seymour open on the wings with Stuart Hogg at full-back. This will be Hogg’s final home game for the Warriors before his summer switch to Exeter Chiefs.
There is plenty of strength on the bench as well with the likes of Ryan Wilson, George Horne, Peter Horne and Huw Jones to call upon.
For Ulster it’s a front-row of Eric O’Sullivan, captain Rory Best and Ross Kane with Ian Henderson and Kieran Treadwell in the engine room.
At the back of the pack there is a serious amount of power with Nick Timoney, Jordi Murphy and Marcel Coetzee on the flanks and at No 8 respectively.
John Cooney continues alongside Billy Burns in the half-backs, while Stuart McCloskey and Luke Marshell are in the centre.
Louis Ludik begins the game on the left-wing with Robert Baloucoune on the right and Jacob Stockdale moves to full-back for the clash.
Just like the home side Ulster have depth on the bench with Rob Herring, Sean Reidy, David Shanahan and Darren Cave among those ready to play their part.
Speaking ahead of the final-four clash Ulster head coach Dan McFarland, whose side have gone further this season than most expected, is looking forward to testing his team against one of the best teams in the league.
“We’re treating it as an opportunity to play against a quality side and are confident in the work we’ve done this week, but understanding it’s a difficult task. It’s what you want to be doing. We could be on our sun loungers now, but we’re playing play-off rugby which is brilliant,” he said.
The prize for the victor will be a place in the final against either Leinster or Munster who face off in the other semi-final on Saturday and from there who knows what could happen with all hoping to claim the Pro 14 title after another incredible season.
Munster confirm Zebo signing
This co-funded contract will see Munster’s all-time record try-scorer return from Racing 92 and line out for his home club where he made 144 appearances and scored 60 tries between 2010 and 2018.
In his third season with the Top 14 side, the 31-year-old has played 55 times and scored 21 tries to date.
Head Coach Johann van Graan said, “The opportunity to bring Simon back to Munster came about in early April following a final review of our squad’s budgetary position for season-end and with assistance from the IRFU to support what we believe is a really good deal for Munster and Irish Rugby.
“Simon’s desire to return to Ireland and play with his home club is illustrated by his willingness to sign at a level below his market value elsewhere. This has made bringing the province’s all-time leading try-scorer back home, possible.”
Simon Zebo said, “I am thrilled and honoured to be coming back home to play for Munster. My family and I have been so lucky to have enjoyed three incredible years with Racing 92 in Paris and I cannot thank the team there enough, I really have made friends for life and take with me some brilliant memories.
“However, as everyone knows, Munster holds a very special place in my heart and I’ve always said that I wanted to play for them and potentially Ireland again, so when this opportunity arose the lure of being close to home, family and friends and Munster fans, it outweighed all other options. I cannot wait to get back to the HPC with the team and hopefully a packed Thomond Park.”
Ulster Rugby agree to release Coetzee early
Marcell Coetzee has played his last game for Ulster Rugby.
With back-row, Marcell Coetzee, currently side-lined with a hamstring injury, Ulster Rugby has agreed terms which will see the player released from the club at the end of this month, ahead of his planned departure at the conclusion of the 2020/21 season.
Given the need for several weeks of rehabilitation following the injury sustained by Coetzee in last month’s Guinness PRO14 fixture against Leinster, Ulster Rugby and the player have reached a mutual agreement to part ways on Friday 30 April.
Head of Rugby Operations and Recruitment, Bryn Cunningham, said: “We have come to an agreement that will allow Marcell the time and space required to continue his rehab.
Lowry retained at 10 for Ulster v Zebre
21-year-old, Cormac Izuchukwu will make his first start for the Ulster men as he is named in the second row alongside Kieran Treadwell. Marty Moore comes back into the starting front row at tighthead, with Eric O’Sullivan and John Andrew retaining their starting berths at loosehead and hooker. Jordi Murphy will captain the side at openside flanker, with Sean Reidy and David McCann being retained at blindside and Number Eight.
A youthful back line sees Ethan McIlroy coming into the back three at full-back, with Rob Lyttle on the left wing and Robert Baloucoune returning on the right. Stewart Moore and James Hume will make up the midfield pairing, while John Cooney and Michael Lowry are named at half-back.
Brad Roberts, Callum Reid, Tom O’Toole, Alan O’Connor and Matty Rea are the forward reinforcements, with David Shanahan, Ian Madigan and Ben Moxham providing the back line options on the bench.
