Manchester United midfielders Paul Pogba and Bruno Fernandes have both suffered injuries following a collision in training.
Fernandes came off worse following the accidental clash, as reported by The Mirror.
United were preparing for Saturday's Premier League game at home to Bournemouth.
Fernandes, who has excelled since joining United in January, is said to have come off worse
Pogba and Fernandes have struck up an excellent partnership in recent games, and it would be a major blow to United if they were to be without either or both of them, even for a short period.
