BEN Westwood could miss out on Warrington Wolves' Challenge Cup semi-final clash with Hull KR on Saturday.

The forward has been charged with making a Grade B shoulder strike on Luke Gale in the fourth minute of the game against Castleford Tigers.

He faces a potential ban of one to two games.

Westwood was charged after the incident on Sunday was viewed by the RFL Match Review Panel. He will appear before an independent disciplinary tribunal on Tuesday evening.

Westwood does not have the option of an early guilty plea after submitting an EGP after the game against Catalans in June.

He served a one match suspension then for dangerous contact.
