Gary McAllister says he will leave any decision surrounding Jermaine Beckford's fitness until late, ahead of Thursday's Play-Off semi-final second leg at Carlisle.

Our leading goalscorer returned from an ankle injury to play a part in Monday's first leg, but he was withdrawn with less than an hour on the clock.

The striker is now facing a race to be fit for part two of the clash at Brunton Park, and the boss says he will wait before making a firm decision on whether to name Becks in his starting line-up.

"It was plain to see on Monday he wasn't 100 per cent fit," said the boss. 

"We took a gamble and barring a fantastic save from Westwood he would have got us a goal.

"I've got a tough decision now in the next day or so. He's responded to treatment again, and it's settled again, but we'll wait and see.

"It'll be a late call."

Tresor Kandol and Anthony Elding will be the players on standby to partner Dougie Freedman up front if Beckford fails to shake off the problem.

The boss will take an unchanged squad to Brunton Park, with Alan Thompson named among the 20-strong travelling party.

The experienced midfielder is now fit again after injury, and could come into the reckoning for a place on the bench for the must-win clash.

"He is travelling with us and he is part of the squad," confirmed the boss.

United head to Cumbria aiming to overhaul a 2-1 deficit to book at place at Wembley in the Play-Off final on Sunday May 25.
