Leeds United may have received a huge injury boost ahead of the visit of Manchester United, with Stuart Dallas spotted in action at Thorp Arch on Friday evening.

The Lowdown: Dallas an injury doubt

The Whites face one of their biggest games of the season on Sunday afternoon, welcoming bitter rivals Manchester United to Elland Road for what could be a ferocious match.

It is also a vital 90 minutes in Leeds' quest to pull clear of the relegation zone, with last weekend's 3-0 loss at Everton further sending them towards the drop zone.

Dallas has been an injury doubt all week after limping off early at Goodison Park, but some positive news may now have emerged.

The Latest: Back in training

As pointed out by Leeds All Over, an official club video on Twitter shows Dallas training with his teammates, suggesting he could be available to face the Red Devils.

Incredibly, the 30-year-old hasn't missed a league match for Leeds since July 2020.

The Verdict: 'Massive'

Dallas, hailed as 'outstanding' by Paul Robinson, has been such a great servant for the Whites, not only showing great dependability but also quality, scoring eight Premier League goals last season.

His versatility also makes him a key figure - he can thrive in midfield or in either full-back role - which has been priceless in such an injury-plagued campaign.

Having Dallas available on Sunday will immediately enhance Leeds' hopes of picking up a famous win against Ralf Rangnick's side, with Robinson saying the impact of his injury would be 'massive'.
