Steve Boxall has been told not to hurry back into action for Belle Vue Aces by team manager Chris Morton.

The 20-year-old dislocated a shoulder at Coventry before popping it back into place at the side of the track.

The ensuing soreness has forced him out of Thursday's Elite League match at Swindon where Robert Ksiezak deputises.

"We are not sure yet when Boxall will be ready to come back and he has been told to rest his shoulder," Morton told the Manchester Evening News.

He added: "He has been told to rest his shoulder so we'll have a better idea when he can start to move it and do some work with it.

"It's so important he does not rush back because you can't be too careful with an injury like this.

"It has not happened to him before but it's well known in speedway you can have an on-going problem with a dislocated shoulder."
