Bayer Leverkusen right back Timothy Fosu-Mensah is out for the rest of the Bundesliga season with a serious knee injury.
The former Manchester United player tore his ACL in Leverkusen's loss to Freiburg on Sunday.
"It's a tough blow for Timothy," Leverkusen sporting director Simon Rolfes said on Monday.
"We'll do our utmost to support him so that he comes back stronger from this difficult situation."
Fosu-Mensah moved to Leverkusen from Manchester United in January and has been in the Bundesliga club's starting team five consecutive times as they struggle to fill the right back position.
Santiago Arias, who was loaned from Atletico Madrid last year, is still out due to a fractured fibula and Lars Bender is also unavailable due to a meniscus injury.
Leverkusen, who were top of the table mid-December, have won only two of their last 10 games.
