He played the full game against Wigan and was walking around with everyone at the end no problem.

Not injured. Just not picked.

He could have been injured doing anything it might not be rugby related. If he has been dropped however given our current injuries my prediction of him not having a future at Saints looks right.

Is he out of favour?

Always thought he and Lomax were your most promising youngsters.

Gaskell if not injuried should feel unlucky not to be picked now lomax and wilkin are out

Maybe Gaskell and the coaching staff have concluded that, at this time, he'll be better served learning more of his craft and rebuilding his confidence in the 'reserve' team. Don't forget that Rush has been his mentor at Saints and knows him as a player better than anyone (and, one would assume, Gaskell has trust in Rush)
