Manchester United forward Romelu Lukaku has reportedly suffered a hamstring injury which could keep him out of the rest of the season.

Lukaku has endured a mixed campaign for United, with just 14 goals coming from 41 outings in the Premier League and Champions League, and it has led to speculation regarding the player's future at Old Trafford.

According to The Mirror, Lukaku may have already played his last game for United, having sustained a hamstring problem over the past few days.

The report claims that the Belgium international is currently being assessed, but United fear that they will be without the 25-year-old for their Premier League fixtures with Huddersfield Town and Cardiff City.

Manager Ole Gunnar Solskjaer is also having to deal with a shoulder injury to Marcus Rashford.
