Manchester United manager Sir Alex Ferguson has confirmed striker Javier Hernandez picked up ankle ligament damage in yesterday's 1-0 win over Aston Villa.
The Mexican international was substituted early in the first-half after falling in the box, with Chicharito appearing to catch his studs in the turf before twisting awkwardly to the ground.
Ferguson's fears were quickly realised after the forward was stretchered off the pitch, and the Scot confirmed post-match that the player will be out of action for around a month.
"I think it is torn ligaments in the ankle and he’ll be out for four weeks," said Ferguson.
"We are having a bad time with injuries at the moment but that is why we have a strong squad."
Hernandez will miss the busy festive period for the Red Devils, starting with the crucial Champions League group match against FC Basle in midweek.
United do have Danny Welbeck back in the ranks and fit again however, and Ferguson was happy to give the England striker 15 minutes in the closing stages at Villa Park.
"Danny Welbeck is fit again and fortunately he got 15 minutes (against Villa) which is good, so he is an option for Wednesday. He has not had a lot of football recently which is something I have to consider," added Fergie.
"But Nani did alright through the middle and Valencia did very well for us when he came on, he was excellent.
"So I have some options up-front. We may have Berbatov fit for Wednesday also, but we are getting our fair share of injuries at the moment."
