Berlin, April 17 (IANS) Chile midfielder Arturo Vidal is due to undergo surgery for a knee injury, preventing him from participating in Bayern Munich's upcoming matches, the Bundesliga club have announced.
Bayern coach Jupp Heynckes said Vidal, 30, sustained the right knee injury during the club's training session on Sunday, reports EFE news agency.
"Arturo has a loose body in his knee. That's preventing him from stretching. He's already on his way to Augsburg (to Dr. Ulrich Boenisch). He needs keyhole surgery on his knee," Heynckes said during a press conference on Monday.
"Arturo will definitely be out of action for a while," he added.
Vidal is likely to miss Saturday's Bundesliga game against Hannover and next week's key duel with Real Madrid in the first leg of the Champions League semi-finals.
