Saidy Janko faces a lengthy injury lay-off just weeks into his Barnsley career, according to a report.

The on-loan Celtic full-back has begun his season-long loan with the Championship club in eyecatching form but missed last Saturday’s 2-0 defeat to Brighton.

Reds boss Paul Heckingbottom revealed that Janko will be out for until at least the middle of next month in a major blow to the club.

“Saidy’s torn his thigh and will be out for a few weeks, Heckingbottom said, as quoted by the Sun. “It’s disappointing because he’s come in and made an impact from the bench.

“We were looking at getting him to start games as we came into this busy period, but he’s out of the picture now until after the international break.”

Manchester United academy product Janko has scored one goal from two sub appearances since joining on loan in August.

Janko, 20, moved to Barnsley on a season-long loan from Celtic in the final days of the summer window.

The right-back began the campaign in Brendan Rodgers’ team, featuring in seven matches before he was deemed surplus to requirements.

The Scottish giants revealed on their official website and Twitter account that the right-back will spent the entire 2016-17 campaign at the Championship club.

The defender joined Celtic in the summer of 2015 from United but an ankle injury limited him to just 13 appearances in his first season at Parkhead.

In other Celtic transfer news, the club’s defender deal collapsed at the eleventh hour on deadline day.
