The attacker missed Eintracht Frankfurt's 3-0 defeat away to FC Bayern München on Saturday with a knee complaint, and on Monday afternoon the club announced that he would miss the rest of the season.
Meier: 'It's a massive shame'
"Tests in Basel revealed that Alex Meier's injury is more serious than first feared," read a statement on the club's official website. The 32-year-old will undergo corrective surgery on Tuesday and will therefore play no further part in the Eagles' campaign.
"I'm very sad that I have to have an operation," Meier said. "It's a massive shame that I can't finish the season and help the team out anymore. I'll keep my fingers crossed for the lads and hope they can finish the season off successfully. For me the only thing that counts now is to recover as quickly as possible."
Coach Thomas Schaaf also expressed his regret at Meier's absence: "Losing Alex has hit us hard because we'd hoped he'd be able to help us with more goals in the remaining games this season. Now we hope Alex comes through the operation well and that he can get back to fitness as soon as possible."
