Darron Gibson's proposed move away from Manchester United has reportedly been cast into doubt after the midfielder suffered an ankle injury in training that could keep him out for a month.
According to The Guardian, the Gibson - a target for Aston Villa and Blackburn - damaged his ankle ligaments on Thursday and is now highly unlikely to be sold this summer.
Sunderland have also been linked with the 23-year-old, who does not appear to feature in Sir Alex Ferguson's long-term plans at Old Trafford.
The retirement of Paul Scholes had afforded Gibson the opportunity to stake his claim for a regular starting berth in the United midfield, but Tom Cleverley's emergence seems to have put paid to the ambitions of the Republic of Ireland international.
And, with reports suggesting United are still interested in signing Wesley Sneijder, it will further hamper Gibson's progress with the club.
Gibson joined the United academy in 2004 and, between loan spells with Royal Antwerp and Wolves, he has made 58 first-team appearances for the Red Devils.
