Both Darragh Ryan and Adrian Fenlon, who missed the quarter-final game against Antrim, have been included at full-back and right half-forward, respectively.
The selectors made it clear after the formal announcement that they were sufficiently happy with the progress of the two players to include them. And while Fenlon will be given a fitness test tomorrow, there is no real doubt about him being able to line out.
"We feel the two lads are going to be okay," said manager John Conran. We're giving Adrian a final fitness test on Friday evening, but we think he is fine to play. And Darragh is fine to play."
Pointing out that last night's training session in Wexford Park marked the end of their preparations, he added: "we're hoping for the best. That's it. They have given it everything." Darragh Ryan suffered a broken bone in his (left) hand in the qualifier game against Waterford. He had plaster removed earlier than expected and will be wearing a protective glove.
Fenlon pulled a hamstring early in the same game and had to come off. In that game he had started at centre-forward.
Their return results in the demotion of Colm Kehoe and Chris "Hopper" McGrath. Doc O'Connor moves from full-back to the left corner with Dave Guiney named on the other side.
In attack, Fenlon takes over the position occupied by Mitch Jordan, who switches to the right corner in place of McGrath. Brothers Rory and Michael Jacob sons of former great Mick Jacob are both featured in the attack.
Seán Óg de Paor remains an extremely doubtful starter for Galway's clash with Donegal in the All-Ireland SFC quarter-final replay at Castlebar on Saturday. The dynamic Galway wing-back missed last weekend's thrilling drawn game because of a groin injury sustained in a club game and was replaced by Kevin Brady.
Meanwhile, Tipperary are hopeful that Tomás Dunne will be able to resume light training at the weekend, just a week before the Premier County's Guinness All-Ireland SHC showdown with arch-rivals Kilkenny at Croke Park on Sunday, August 17.
Dunne tore ligaments in his ankle in Tipperary's victory over Offaly and was on crutches for a week as a result. He has not trained so far, but manager Michael Doyle expects his ace performer back on the training ground by the weekend.
Good news also for Tipp is that goalkeeper Brendan Cummins is in no danger of missing the semi-final after receiving a blow on the thigh during the Offaly game.
