West Ham United midfielder Lucas Paqueta is facing four weeks on the sidelines.
The Brazilian had to come off during their 1-1 draw in the FA Cup with Bristol City on Sunday.
The problem is with his knee, which has been giving Paqueta issues in the past.
Per The Mail, West Ham will now take it easy to ensure that he does not miss more game time.
With a two-week break from the action upcoming in the Premier League, Paqueta may not miss too much game time.
The Hammers have concerns about the fitness of key forward Jarrod Bowen as well.
