Manchester United striker Romelu Lukaku could miss tomorrow's game with Watford depending on an FA investigation into whether he kicked an opposition player in their last game.

Lukaku inexplicably appeared to kick out at Gaetan Bong twice in quick succession during Saturday's 1-0 win at Old Trafford.

It was not noticed by referee Neil Swarbrick, and if there is no mention of the incident in his official report - which is sent into the FA on a Monday morning - then Lukaku could find himself in hot water.

The association are already considering whether to take further action, and if they do he will likely be banned for three games, ruling him out of tomorrow's game at Vicarage Road.

The fixture will already see the return of one striker banned retrospectively, with Troy Deeney free for selection at the conclusion of his three-match ban for raising his hands to Joe Allen in last month's defeat to Stoke City.
