Dungannon have cited St Mary’s second-row Gareth Logan for an incident during last weekend’s AIL match at Templeville Road.
Dungannon flanker Mike Haslett suffered a serious facial injury during the first half. Haslett had his jaw broken in two places in an incident missed by the referee and both touch judges.
St Mary’s are understood to have preempted any punishment that may be handed to Logan by suspending their player for six months.
