Ratchford could face lengthy layoff

Stefan Ratchford could be set for an extended period on the sidelines, after being seen on crutches at the weekend.

The Warrington utility was walking around the Olympic Stadium on crutches, heightening fears of a serious knee injury.

He is expected to go for a scan this week, with the Wolves hopeful that he has avoided serious injury.

Ratchford did not feature in the Four Nations, with his only appearances coming in the warm-up game against France.

He made 32 appearances for Warrington last year, scoring 10 tries.
