The injury, which has still to be diagnosed, will see the striker miss Saturday’s SPL clash against Aberdeen at Pittodrie and also next week’s cup replay date with the Gers.

However, Peter is confident he has enough striking options at his disposal to cover the 21-year-old’s absence.

He said, “We’re still finding out if it’s a pull or a tear, but the likelihood is Damian will be out for two weeks at least.

“The one good thing is we’ve got options up front to replace him in the time that he’s out.”

Those options include David Goodwillie, Jon Daly, Andis Shala, who scored in the draw at Ibrox, and Francisco Sandaza, who is getting ever closer to full fitness and featured as a substitute at the weekend.

The Spaniard also played for 45 minutes yesterday as United beat Swedish touring outfit Ostersunds 4-2 at St Andrews.

On the scoresheet for the Tangerines were Kevin Smith, David Robertson, Jordan Elfverson and Jennison Myrie Williams, while young defender Keith Watson played the full game.

Meanwhile, Blackpool boss Ian Holloway fears he may have been priced out of a move for Garry Kenneth.

The Championship side had two bids for the towering defender rejected in January. Since then, the 22-year-old Dundonian has gone on to gain international recognition, being included in Craig Levein’s Scotland squad for the recent friendly against the Czech Republic.

And Holloway feels Kenneth’s international call-up will have increased his profile and, undoubtedly, added to his value.

“My chances of landing Garry have been scuppered. His transfer value will be too high for us,” said Holloway.

United and Rangers have agreed to reduce prices for next Wednesday’s Scottish Cup replay at Tannadice.

Tickets for the game went on sale today, priced £16 for adults, £6 students/over 60s and £4 for under 18s.

As well as the home support, United will be selling tickets to Rangers fans for their end of the stadium.
