MARK Percival is named in the Saints 21 man squad ahead of Saturday's Coral Challenge Cup quarter final against Warrington at the AJ Bell Stadium (2:30pm) live on BBC1.

England centre Percival has not featured since picking up a hamstring injury in the win over Castleford on 16 August, but returned to training last week.

Matty Costello makes way for Percival.

The only other change to the 21 man squad following the win over Hull KR last week is young half back Lewis Dodd return following his 14-day period of self-isolation.
