Chile officials have confirmed that Alexis Sanchez has suffered a low grade muscular injury.

CNN Chile claim the forward reported for international duty before pulling out of training early on Tuesday afternoon to undergo medical tests for a suspected torn calf muscle.

This prompted fears that the Arsenal talisman would be sidelined for months in a potentially devastating blow to the team’s title challenge.
The Chile Football Association have now released a statement on their website confirming Sanchez’s injury.
“The Medical Corps of the Chilean National Team reports that player Alexis Sanchez has a low grade muscular injury,” it read. “The athlete will remain in Santiago, under treatment and in evaluation.”

Chile face two important games, against Colombia on Thursday and Uruguay next Tuesday, as they attempt to qualify for the World Cup.

Sanchez could be facing months on the sidelines if further tests confirm a more serious injury to his calf.

Sanchez has been in sensational form for Arsenal this season after being handed a new role as the spearhead of the attack.
