"I can't wait to get out there and represent Ulster in such an important game," said Ferris.
"It's been tough missing the past few weeks, particularly the match against Aironi where there was quite a lot of open play and after that I'm really champing at the bit to get going again.
"I think we'll see a big 'pack against pack' battle and feel that the game will be won and lost up front.
"Biarritz don't like to play too much rugby when they do get front-foot ball it's because of their forwards - that's where it's all going to start for them.
"We will be facing a very good, tough pack row and we'll really have to dig in but we're every bit the match for Biarritz and I'm looking forward to the contest."
Ulster remain unbeaten this season and sit at the top of Pool 3 in courtesy of the 30-6 bonus point victory over fellow Magners League side Aironi.
