Castleford Tigers coach Daryl Powell has revealed that prop Craig Huby is a doubt for Saturday's Challenge Cup final against Leeds Rhinos.

Huby is currently struggling with the fractured elbow that he suffered during his team's semi-final win over Widnes Vikings.

"Rugby league players are tough people. If he's not available we've got plenty of people who can take that slot," Powell is quoted as saying by Sky Sports News.

"But he's obviously a pretty important player for us so I'll give him as long as he needs. We'll make that decision later on in the week."

Castleford have won the Challenge Cup four times, though their last triumph came back in 1986.
