The 30-year-old Socceroos midfielder had to be replaced midway through the second-half of Tuesday's 2-1 Europa League victory over Sporting Lisbon after injuring his calf.

Cahill, who is known for scoring in important matches, will now miss games against the Red Devils, as well as the return-leg against Sporting in Portugal.

Everton boss David Moyes said: "Tim will be out for two to three weeks because he has got a calf strain.

"It is a grade one, it is not serious but I would be very surprised if he could make any of the games in this coming week."
