Herbst returns for A team after nine months of injury
This week's main talking point regarding the Ulster A selection is the long-awaited comeback of Wiehahn Herbst, who today gets his first run-out since January.
The South African tight-head prop starts for the A team at London Scottish for their second outing in the British and Irish Cup (kick-off 2.30pm) after last weekend's 19-6 triumph over Jersey.
Herbst last featured in an Ulster shirt back in mid-January in the penultimate Champions Cup pool game at Saracens where he sustained a toe injury which sidelined the 28-year-old for the rest of the season.
After recovering, Herbst was then back on the injured list again for the start of this campaign following surgery for a groin issue, but now finally gets his chance for some game time again after nine months away.
Selection-wise, Dan Tuohy has been asked to make another appearance for the A side before what is surely his senior return, and is skipper again.
In addition to Herbst coming in for Ricky Lutton - who is injured again - A team coaches Kieran Campbell and Willie Anderson have made three other changes from last week with Angus Lloyd starting at scrum-half and Jacob Stockdale and Robert Lyttle dropping down from the senior team's bench to play at outside centre and right wing respectively with Tommy Bowe doing a direct swap with Lyttle.
Pool leaders London Scottish have made nine changes following their bonus-point win over Cardiff and are in good form having won four of their last five games.
Aaron Cairns, who showed up well against Jersey, is expecting a very different challenge from Scottish.
"They look sharper than Jersey and we know we'll have to be more clinical than last week," he said.
