St Johnstone-Aberdeen preview

St Johnstone midfielder Gary McDonald has not recovered from injury and will miss Sunday's Scottish Cup semi-final against Aberdeen.

McDonald had hoped to recover from a knee injury which has sidelined him for three weeks, but he will miss the chance to play against his former club.

Saints boss Tommy Wright has no other injury problems to contend with as his side look to avenge their 4-0 League Cup semi-final defeat to Aberdeen in February.

Tam Scobbie (ankle) and Murray Davidson (knee) are long-term absentees and not expected to return to action this season.

Aberdeen winger Jonny Hayes has lost his battle to regain fitness ahead of the Ibrox encounter.

Hayes is making good progress from a collarbone injury sustained in the early stages of last month's League Cup final against Inverness Caley.

Dons manager Derek McInnes has decided not to take any chances with the player as the team are still in the hunt for a second place finish in the Scottish Premiership, and may have a second cup final to look forward to.

On-loan Swansea defender Alan Tate and forwards Calvin Zola are both carrying knocks, but will be given a chance to prove their fitness.

St Johnstone v Aberdeen is live on Sky Sports 2 HD from 12.30pm on Sunday.
