Injury update: Ulster rule forward duo out of Scarlets trip in Champions Cup while doubts hang over HIA pair
Ulster have suffered two new injury blows ahead of the Heineken Champions Cup window.
The province have confirmed that neither Andrew Warwick nor Alan O'Connor will make the trip to Scarlets this weekend, having sustained injuries during Saturday's victory over Cardiff Blues at Kingspan Stadium.
Prop Warwick is out with a knee problem while an ankle issue is sidelining second-row O'Connor, who has captained Ulster in recent weeks in the absence of Rory Best.
Out-half Billy Burns is a doubt after undergoing Head Injury Assessment protocol following a clash with former Ulster favourite Nick Williams in Saturday's 16-12 success in Belfast.
Ulster have already welcomed six of their Ireland internationals back into the panel and should add Iain Henderson to that tally in Wales this weekend.
There are, however, doubts hanging over Will Addison's availability after the former Sale Sharks skipper went through HIA following Ireland's win over USA in the final game of the Autumn International
