Frankfurt/Main - Bad news for Eintracht Frankfurt, who will have to do without Sebastian Jung for longer than expected after the 23-year-old right back revealed on his website that what was initially believed to be an adductor problem is in fact a muscle strain.

, who featured in the Bundesliga campaign opener at Hertha Berlin but missed the follow-up at home to Bayern Munich and the Europa League play-off first leg win away to Qarabag Agdam, described the diagnosis as "an extremely bitter blow." He is likely to be sidelined for several weeks yet as a result.

Frankfurt, still without a point in the league this season, are away to newly-promoted Eintracht Braunschweig on Sunday.
