Manchester United could reportedly have to make do without the services of Antonio Valencia for Monday night's trip to West Bromwich Albion.
The winger was replaced by Marouane Fellaini in the 79th minute of United's 2-1 win over Everton at Old Trafford with what seemed to be a hamstring complaint.
Although the injury is only thought to be a strain, it is likely to keep the 29-year-old out of the clash at The Hawthorns, according to the Daily Mail.
Valencia has made five appearances for the Red Devils this season.
