Leicester Tigers flanker Dominic Ryan has been instructed to step down from rugby for 12 weeks following repeated concussions.
The Irish back-rower received a head injury during the 24-11 defeat by Northampton on 9 September after colliding with Saints’ George North when attempting a tackle.
The 27-year-old has since made two more appearances, but will now not be considered for selection to ensure he fully recovery.
Matt O’Connor confirmed the news in his press conference this afternoon ahead of the Tigers’ opening Champions Cup pool game against Racing 92 on Saturday. The English club face Munster in back-to-back games in December.
Ryan joined Leicester from Leinster in the summer and has so far made four appearances for the Tigers.
