Diafra Sakho will undergo a scan on the hamstring injury he suffered during West Ham’s 1-1 draw against Manchester United on Sunday, according to a report.

The Sky Sports website have reported that the 26-year-old has suffered a further setback, having only returned from a three-month lay-off with a back injury.

The Senegal international left the pitch after 66 minutes at Old Trafford, coming off for young forward prospect Ashley Fletcher.

Despite playing in just two fixtures this campaign Sakho also became the first striker to score for the Hammers this season.

The forward opened the scoring within the first few minutes of the clash at Old Trafford, playing a pivotal part in earning his side a vital point at a tough ground.

He could now be a big loss for Slaven Bilic’s side, who are struggling to find form in 16th place.

The Hammers have a trio of hard fixtures ahead of them with a return to Old Trafford in the EFL Cup coming up first on Wednesday.

They will then host Arsenal at the Olympic Stadium on Saturday before travelling to Anfield, where they will meet an in-form Liverpool.

It is likely that one Fletcher, Simone Zaza, Andre Ayew, or even Michail Antonio will replace Sakho in the line-up.

Football Insider verdict:

Another Sakho spell on the sidelines would be a huge blow for West Ham, especially in a difficult period for the club. It is not known how long the striker will be out for now, but West Ham will need all of their players fit and firing for the Christmas period. The winter fixtures can make or break a team’s season and given the Hammers’ current position they will not want to take any chances. The injury has only made it more clear that Bilic needs to add another striker to his squad in January, otherwise they are in danger of suffering a shock relegation by the time the season finishes.
