Jiri Skalak could be handed an FA Cup role against his old club thanks to three team-mates being cup-tied.

But the former Albion wideman is not expected to feature as his Millwall side continue their battle against relegation tonight.

The Lions are one point clear of the drop zone ahead of their trip to Birmingham City.

St Andrew’s is likely to be the centre of much media attention after events on Sunday, when a Blues fan attacked Aston Villa skipper Jack Grealish.

But the focus for Millwall will all be on securing league points as they aim to stay above 22nd-placed Rotherham, who are at QPR.

Skalak moved from Albion to The Den last summer but has been out of favour and has not played in the Championship since Christmas.

He started the FA Cup win over Hull City and went on late as sub when Everton were shocked at The Den in the fourth round.

Three Millwall players are ineligible for their side’s cup run, two of them because they played on opposite sides in a third-round tie.

Ben Marshall, on loan from Norwich, was in the Canaries side which lost 1-0 at home to Portsmouth, who had Ben Thompson on loan from Millwall at the time.

That match rules both players out of cup action for the Lions.

Fred Onyedinma played in the earlier rounds while on loan from Millwall to Wycombe.

Skalak has only made four starts in the Championship for Millwall, as well as nine appearances off the bench.

He last featured in the league when going on as an 89th-minute substitute at home to Reading on Boxing Day.
