Lock Donnacha Ryan is in line for his first Six Nations action this season after making the cut for Ireland's training squad to prepare to face England.
Head coach Joe Schmidt has named a 33-man group that will complete the final preparations for the clash at Twickenham on Saturday.
Ryan returned to Munster duty for the first time since December in Saturday's 36-8 home RaboDirect PRO12 victory over Zebre, having fully recovered from knee surgery.
Unbeaten Ireland take on England chasing their first Triple Crown since their 2009 Grand Slam.
Iain Henderson, Mike McCarthy and now Ryan will compete for a slot on the bench to cover the starting second row pair of captain Paul O'Connell and Devin Toner.
