Tim Swinson has also been released to play, partnering Scott Cummings in the engine room behind a front-row of Alex Allan, Kevin Bryce and Siua Halanukonuka.

Nick Grigg was named Man of the Match in Swansea and he starts alongside Stafford McDowall in midfield.
Nick Frisby and Brandon Thomson are the half-backs.
On the bench, Thomas Gordon is in line to make his Warriors debut after coming through the Scottish Rugby Academy and impressing for Currie Chieftains in the Tennent’s Premiership this season.
Scottish Rugby Academy hooker Robbie Smith could also play his first game for the club.
Meanwhile, Ospreys head coach Allen Clarke has made eight changes, including two positional switches, to his starting line-up which lost to Pau in the Challenge Cup last weekend.

Leinster vs Scarlets
Leinster head coach Leo Cullen has named seven Academy players in his 23 but has been able to recall a number of senior players from injury and suspension as well as handing a potential debut off the bench to Academy forward Jack Dunne.
Rob Kearney is back from injury to take his place as captain at full-back with Barry Daly on the right wing and James Lowe back from suspension on the left.
In the centre Academy back Conor O’Brien and Rory O’Loughlin are again named together having also started against Connacht in the Christmas interpro.
Hugh O’Sullivan makes his first start for Leinster having made his European debut off the bench only last weekend against Wasps. O’Sullivan will have Ciarán Frawley outside him in the number 10 jersey.
In the pack Jack McGrath, James Tracy and Michael Bent are the front-row selected by Cullen with Ross Molony and Mick Kearney in the engine room.
The back-row consists of Max Deegan, Scott Penny and Caelan Doris.
Meanwhile, Steff Hughes will captain the Scarlets this week at the RDS Arena.
As 12 internationals take their place in the Welsh squad for the Six Nations this month, it’s an important time for the younger squad members to step up for the Scarlets.
Scarlets’ squad includes a few tweaks from last week’s game. The internationals are making room for players such as Ioan Nicholas at 14 while Kieran Hardy is at scrum-half, joining Dan Jones at 10 following an accomplished performance against Racing 92.
Josh Macleod continues at number eight with youngster Dan Jones at his side. One international who is available for Scarlets is Jake Ball who has an opportunity to gain some valuable game time before the start of the Six Nations.

Ulster vs Benetton
There are two personnel changes to the Ulster backline that played in last Saturday’s 14-13 comeback win against Leicester Tigers in the Champions Cup, as academy players Michael Lowry and James Hume are installed at full-back and outside centre respectively.
Another academy player, Robert Baloucoune, who scored the match-winning try at Welford Road, is again selected on the right wing.
Dave Shanahan and Billy Burns are retained in the half-back positions, with Stuart McCloskey lining out at inside centre and Louis Ludik named on the left wing.
Up front, Alan O’Connor takes over the captaincy from Rory Best and he will partner Kieran Treadwell in the second-row.
Andy Warwick and Rob Herring join Marty Moore in the front-row, while there are three new faces in the back-row as Ian Nagle, Nick Timoney and Greg Jones have earned call-ups.
Hooker John Andrew will win his 50th provincial cap if he’s called upon from the bench, with Wiehahn Herbst, Tom O’Toole, Matthew Dalton, Clive Ross, Jonny Stewart, Darren Cave and Rob Lyttle also included in the matchday 23.
Meanwhile, Luca Sperandio will line up at full-back for Benetton, with Ratuva Tavuyara and Monty Ioane completing the back three.
At centre, Tommaso Iannone and Marco Zanon combine, while Dewaldt Duvenage is at scrum-half and captain Ian McKinley takes his place outside the South African.
The front-row consists of Nicola Quaglio, Hame Faiva and Marco Riccioni with Irné Herbst and Federico Ruzza at lock.
Finally, the back-row sees Marco Lazzaroni, Michele Lamaro and Toa Halafihi completing the XV chosen by head coach Kieran Crowley.
