Javier Hernandez is recovering after successfully undergoing surgery on a broken collarbone.
The striker suffered the injury during Mexico’s Gold Cup warm-up match against Honduras in Houston on Wednesday night.
Hernandez has scored 40 goals in 73 appearances for his country and he will be a significant loss for the team.
The injury has also come at a bad time for the 27-year-old as his future at Old Trafford is far from certain.

The likes of Liverpool, Inter Milan, Juventus and MLS outfit Orlando City have been linked with a move for the player, with United valuing him at £8m. However, with his injury and subsequent recovery it is unclear whether van Gaal will still be able to command that fee for him.
