Mayo received a boost this weekend when it was reported that Aidan O'Shea's knee injury, incurred in training last week, wasn't as bad as initially feared.
The 30-year-old Breaffy man limped out of a training session in MacHale Park eight days ago, Mayo's first since the loosening of Covid-19 restrictions on 19 April.
However, the player has since undergone a scan and Midwest Radio is reporting that the injury isn't as bad as was previously thought and say that O'Shea should be fit in time for the commencement of the Allianz Football League on 15 May.

Speaking to RTÉ Sport, O'Shea's inter-county teammate Cillian O'Connor said he was hopeful the player would be back in time for the return of competitive action.
"I've not heard anything for definite now yet," said O'Connor. "Still optimistic that he'll be alright. It was just a kind of a contact injury as opposed to a muscle or a soft tissue, so not really one that can be avoided. Just a bit of chance.
"I think he has to wait for a second reading on a scan or something before he'll know for sure. Still hopeful that it won't be anything too serious.
O'Shea, a three-time All-Star, has not missed a championship match since 2012 and O'Connor paid tribute to his impact within the set-up.
"He's been huge. He hasn’t missed a game really as much as I can remember in 10 or 11 years.
"Behind the scenes, he’s barely missed a training session in the same time. He’s just a real good standard-setter around the place and would be one of the best trainers consistently in the group.
"Every now and again we have a game and the country sees a performance but all the while, behind the cloak, he's driving things on in training for six, seven, eight, ten sessions between games and that’s really where the big value is in him for us. I’m looking forward to knocking off him and all the lads in training in the next few weeks."
