The Daily Mail says it can be revealed Downing required twelve stitches to an Achilles heel wound he sustained during the 4-1 defeat the Hammers suffered at Anfield on Saturday.
The amount of stitches emphasised the extent of the wound and a West Ham source said: "Ideally we would like to think Stewart will be back in action in a couple of weeks.
"But it's a part of the body where it is difficult to train with the ball until it has fully healed. We will just have to wait and see."
