Manchester United have suffered a massive injury blow as Timothy Fosu-Mensah is set to be sidelined for the rest of the season with a shoulder injury.

The 19-year-old came on as a substitute in his side's goalless draw against Manchester City at the Etihad on 27 April. Jose Mourinho introduced him in the final quarter of the match after Marouane Fellaini was shown the red card for headbutting City striker Sergio Aguero.

Fosu-Mensah left the Etihad with a dislocated shoulder and the Portuguese tactician confirmed the Dutchman's injury after the Manchester derby. According to the Telegraph, the teenager will not feature for the Red Devils after initial scans revealed his worst fears.

The versatile player, who can play anywhere along the back four and in the defensive midifielder role, will undergo further tests. This is to determine if there is any significant damage to the shoulder ligaments.

Fellaini's red card will force him to miss the next three domestic fixtures, meaning he will miss the league clashes against Swansea City at home, followed by two away trips to Arsenal and Tottenham Hotspur.

Paul Pogba also picked up a hamstring injury in United's 2-0 league win over Burnley, forcing him to miss the derby. Mourinho confirmed the France international will miss Swansea's trip to Old Trafford on 30 April and the midfielder should be fit in time to face Celta Vigo in the Europa League.

In addition, United have defensive injury crisis as Marcos Rojo has been ruled out for the rest of the season. The Argentine international joins striker Zlatan Ibrahimovic in the injury list as the duo suffered "significant" knee injuries against Anderlecht.

Chris Smalling and Phil Jones are also struggling with injuries, leaving the former Real Madrid and Chelsea manager with Eric Bailly and Daley Blind as the only two first choice centre-backs in the squad. Fosu-Mensah becomes third player, after Rojo and Ibrahimovic, to be ruled out for the rest of the campaign.
