There are two games on the Champions Cup schedule on Friday with Harlequins hosting Ulster and Racing 92 face Ospreys at Paris La Defense Arena.

Harlequins v Ulster

Kyle Sinckler will captain Harlequins for his first home appearance of the season, with Santiago Garcia Botta returning to the squad at loosehead prop following his recent wedding.

Will Evans returns to the side after being rested for the last two weeks, alongside the explosive Semi Kunatani at flanker and Alex Dombrandt at number eight. James Chisholm is back amongst the replacements following his rehabilitation from injury.

Argentine Martin Landajo starts alongside Brett Herron who makes his first Champions Cup appearance for the club with Fijian winger Vereniki Goneva also starting his first game for the quarters, on the opposite wing to the returning Cadan Murley.

Head of rugby Paul Gustard said: “We were disappointed to come away with the one-point loss in Ulster last weekend and we have been working hard this week to assess the critical few and put our energy into those.

“The players have taken good ownership of the week and driven the detail and energy. We look forward to welcoming Ulster to what we hope will be a noisy Stoop on Friday night.

“It is a great opportunity for a couple of our players who are returning from injury to move the jersey forward in what is a must win game for us if we are to have a chance of competing in this competition.”

Meanwhile, the Ulster coaching team have made two changes to the side that defeated Harlequins last Saturday in the first of two back-to-back games against the English Premiership team.

Versatile back Matt Faddes returns to the starting Ulster side on the right wing, joined in the back three by Jacob Stockdale, who retains his position at full-back, and Louis Ludik, who switches over to the left.

In the midfield, last week’s man of the match Stuart McCloskey is once again paired with Luke Marshall. The familiar half-back duo of Billy Burns and John Cooney is also retained.

The second change sees Kieran Treadwell return to start alongside captain Iain Henderson in the engine room. In the front-row, Eric O’Sullivan will start at loosehead prop, Rob Herring at hooker, and Marty Moore on the tighthead side. Sean Reidy, Jordi Murphy and Marcell Coetzee all keep their places in the back-row.

On the bench, Adam McBurney, Andrew Warwick, Tom O’Toole, Alan O’Connor and Matthew Rea will provide the forwards backup, and David Shanahan, Bill Johnston and Craig Gilroy are the backline reinforcements.
