Bayer Leverkusen attacker Martin Terrier is out for the season with an Achilles tendon rupture, the club said in a statement on Sunday.
The defending Bundesliga champions were already without injured forwards Victor Boniface and Amine Adli.
Seven minutes in to Saturday's 3-1 home win over Borussia Moenchengladbach, Terrier fell to the turf clutching his lower leg without an opponent making contact.
Leverkusen issued a statement on Saturday saying an MRI had "confirmed a rupture in the right Achilles tendon."
"It's a hard blow for Martin and for us as a club," Leverkusen sporting director Simon Rolfes said, with Terrier to undergo surgery on Monday.
The 27-year-old Terrier joined Leverkusen in the summer from Stade Rennais and has two goals and an assist in the league this season.
