The Ospreys have added 20-year old Olly Cracknell to the 38-man squad registered for the European Rugby Champions Cup ahead of Saturday’s return game against Racing Metro.
Tournament regulations allow each team to make two changes to the squad during the pool stages, one of which must be a front-row forward.
Last week, 21-year old loose head prop Gareth Thomas was added to the squad, with Cracknell the second change to be made. He replaces second row De Kock Steenkamp who has been sidelined long-term with an Achilles injury.
Having signed for the region in the summer from RGC, the Leeds born Wales U20 blindside has yet to feature for the Ospreys in competitive action.
