The Armagh talisman missed the Ulster final defeat against Tyrone but the Orchard boss is hoping that the Silverbridge player has a hand in events at Jones Road on Sunday where the young Ulster side play the Munster champions Cork, who defeated Kerry by a point last time out.
"Certainly Peter was a big miss for us in the Ulster final," stressed McShane. "We hope he will play some part at the weekend but if he doesn't make the cut, we'll be looking to other players to take responsibility.”
Last season, Armagh minors bridged a 60 year gap when winning the All-Ireland title, but struggled greatly in the provincial decider against a strong Tyrone team.
Another injury worry surrounds young Wolfe Tones player Ruari McCaughley who was forced to retire early with what appeared to be a shoulder injury in last weekend's club championship game.
Armagh, however, are still looking forward to the Cork challenge according to Paul McShane who said: "We had two good training sessions last week and the boys would appear to have recovered from their Ulster final defeat. At this stage there are no easy games but hopefully we can give a goot account of themselves on Sunday".
Armagh fans will, no doubt, be outnumbered on Sunday and the young Armagh Minor side will be hoping to silence a partisan crowd who will be in attendance to support both the Rebel county's Minor and Senior teams.
But they will be cheered on by former Armagh Captain and All-Ireland winner Kieran McGeeney who will be hoping to spur his adopted Kildare outfit to victory over Meath in their All-Ireland quarter-final tie.
