Marcelo Bielsa has conceded Leeds United will probably be without the services of midfielder Adam Forshaw for their clash with Championship leaders West Brom on Tuesday night.

Forshaw made his return from injury as a half-time substitute during Leeds' 1-0 defeat to Charlton on Saturday, but it now appears the 27-year-old is set to miss the Whites' next match after suffering another injury setback.

The former Middlesbrough man has made eight appearances for Bielsa's side this season, but he was absent from midfield during Leeds' two matches following the international break against Barnsley and Derby County.

It has now emerged that Forshaw looks likely to sit out his third match of the season through injury, with Bielsa also admitting that Pablo Hernandez is still yet to recover from his muscular problem in time for tomorrow's match.

"Probably Pablo and Adam are not going to be in the group," Bielsa told Leeds Live.

"The last match before the international break, he [Forshaw] had a little problem and he cannot solve it."

Forshaw initially suffered his injury during Leeds' 1-0 defeat to Swansea just before the international period, but this did not stop the midfielder from completing the full 90 minutes in the match.

The Verdict

This is another big loss for Leeds as Forshaw is a dependable presence in their midfield, and this revelation makes you wonder why he was fielded against Charlton when not fully fit.

It seems that Leeds' 1-0 deficit at the break may have forced Bielsa into making a decision he was not fully comfortable with, as there must have been an existing concern that Forshaw's injury may re-surface given his quick return.

Bielsa did not put a timeframe on Forshaw's fresh setback so there is every chance he is now set for another spell on the sidelines, and this has not come a good time with Leeds desperately in need of re-discovering their rhythm against West Brom.

Forshaw is a vital cog in Bielsa's system with his ability to break up play and also protect the defence so Leeds will be hoping this is not a major setback, but he should definitely not be rushed back into action again.
