Shakhtar Donetsk midfielder Ivan Petryak may miss the end of the season.
Petryak underwent surgery due to an injury. Now he is already training on an individual programme.
Petryak last practised on 16 March in a match against Feyenoord (1-7) in the Europa League. Since then Ivan has never featured in the Pitmen's starting line-up.
This season he has scored 1 goal and 1 assist in 13 UPL games.
