David Clarke has been ruled out of tomorrow evenings Super 8’s meeting with Donegal.
Midwest Sport understand that the two-time All-Star picked up an injury in training this week.
He will be replaced between the posts by Robbie Hennelly.
There is also concern over the fitness of Donal Vaughan who is also believed to have picked up a knock earlier this week.
Speculation is rife that Tom Parsons who hasn’t played a competitive game for Mayo since that horrific injury last year is going to be included in the 26 man match day squad tomorrow.
Paddy Durcan, Keith Higgins and Matthew Ruane are all available for selection with uncertainty remaining over the return of Diarmuid O’Connor.
The official team won’t be released until lunchtime tomorrow.
