Joe Riley has returned to Manchester United after temporarily cutting short his loan spell at Sheffield United, it has been confirmed.

The left-back, 20, has dislocated his shoulder in a “freak accident” in training with the League One club and has headed to Old Trafford to undergo tests.

United manager Chris Wilder has revealed that Riley could be out for the rest of the season, which would mean his temporary return to United would become a permanent one.

“It was a bit of a freak accident in training, something out of nothing. He stumbled and dislocated his shoulder,” Wilder told BBC Radio Sheffield, as quoted by the BBC Sport website.

“It is desperately back luck for Joe and ourselves. It’s not looking good for him in the short term.

“He has gone for a scan back at Manchester United. Those results will determine if he’s back with us or if that’s his season done.”

Riley joined the Blades on loan from United in the January transfer window in a deal that runs until the end of the season.

Riley is a product of the prolific United academy that has produced a number of players for the first team in recent seasons, most notably Marcus Rashford.

Riley has changed position at an early age after initially being used at right midfield for the youth teams of the Premier League giants before regularly slotting into a defensive role.

He was handed his first-team debut by former manager Louis van Gaal last season and made two appearances for the club.

But he has not been able to force his way in under Jose Mourinho, who gave the green light for him to continue his development at a lower league club.

Riley has featured in just two matches for United after being an unused substitute in four of the six games for which he was available for selection.

In other Manchester United news, the club are also closing in on another defender deal.
