Nigerian winger, Nathan Tella, is yet to recover from a knee injury sustained in September, Nigeriasoccernet.com reports.
Tella returned to training earlier this month but is still working towards regaining full fitness.
Bayer Leverkusen head coach, Kasper Hjulman,d revealed that the injury was more serious than initially thought, saying: "With [Nathan] Tella, [the injury] was more difficult and complicated than we first thought. I think he'll need the international break as well. It's looking better and better, but I can't say when [he'll return] exactly."
The update means Tella will likely miss Bayer Leverkusen's upcoming fixtures, including Nigeria's 2026 FIFA World Cup playoffs against Gabon in November.
The winger has made four appearances for Leverkusen this season and has been a key player for the club.
