Collum a doubt for Tipp

Tipperary centre back Sean Collum is a doubtful starter for the Premier County ahead of next Saturday's All-Ireland qualifier against Carlow in Semple Stadium.

The influential defender, easily Tipperary's most impressive against a rampant Kerry last weekend, limped out of the Munster semi-final at Tralee having damaged his groin and left a gaping hole upon departure.
