London, Mar 5 (IANS): Manchester United have suffered another injury blow with the news that Chilean forward Alexis Sanchez could be out for two months.

The news was shared by Chile national team doctor Pedro Onate, writing in the 'El Mercurio' newspaper, reports Xinhua news agency.

Sanchez was forced to limp out of United's dramatic 3-2 win at home to Southampton on Saturday, and Onate said he had suffered "medial ligament distension" in his right knee, which will sideline him for "between six weeks and eight weeks."

The news is another blow for Sanchez, who missed six weeks earlier in the season with a hamstring problem and has struggled for game time under both Jose Mourinho and his replacement Ole Gunnar Solskjaer.

So far, Sanchez has made only 17 league appearances totalling less than 800 minutes, and has scored just one goal for the club. If he fails to recover in less than two months, his season will effectively be over.
