• FA set to complete review of referee's report on Tuesday
• Newcastle examining their legal options
Callum McManaman is expected to be charged with violent conduct on Tuesday over the tackle that put Newcastle's Massadio Haïdara in hospital but was described as "clean as a whistle" by the Wigan chairman, Dave Whelan.
Whelan issued a vigorous defence of McManaman as the Football Association prepared to complete its review of the match report submitted by the referee, Mark Halsey, which should happen on Tuesday. McManaman faces a three-match ban if charged and found guilty by the governing body.
Newcastle are awaiting results of a scan on Haïdara's left knee after he was taken off on a stretcher at the DW Stadium on Sunday following a dangerous challenge by McManaman, who was making his Premier League debut.
The club are understood to be examining their legal options with a view to potentially taking action if Haïdara is sidelined for a significant period. The initial signs are, though, that the damage may not be as bad as first feared.
The incident sparked a half-time mêlée between Newcastle's assistant manager, John Carver, and the Wigan coach, Graham Barrow, who were both dismissed by Halsey and could receive further punishment from the FA.
The referee took no action against McManaman during the game but the FA can take retrospective steps against the Wigan midfielder provided Halsey confirms he did not see the incident and would have issued a red card had he done so. Alan Pardew, the Newcastle manager, claimed Halsey admitted he missed the collision when they spoke at half-time.
McManaman has been an influential figure in Wigan's FA Cup run this season and will miss the semi-final against Millwall at Wembley on 13 April if found guilty of violent conduct. The 21-year-old did make slight contact with the ball before his wild challenge caught Haïdara's knee and Whelan, who suffered a broken leg in the 1960 FA Cup final, issued his vehement support of the Wigan midfielder on Monday.
The Wigan chairman said: "The ball was there and McManaman got the ball as clean as a whistle, then followed through and they collided. He hasn't gone over the ball. That's an accident.
"From Wigan Athletic we want to say to that lad we hope he's fit to play next week or a fortnight because we don't wish ill on any of the opponents we play against. Football being football, it is a tough game and these accidents do happen.
"I think the ball was in between them, they've both gone for it fairly and the follow-through is where the collision is. You can't just drop your foot or stop. They are both going at each other at 18 or 20mph and they collide. It happens."
Whelan also claimed there were no complaints from the Newcastle hierarchy about the tackle following their controversial 2-1 defeat. He added: "I spoke to [Newcastle's managing director] Derek Llambias after the match and I have to say the Newcastle people who we dined with took it all on the chin and thought, 'Yeah, it is part and parcel of the game.' I know there were some bad things said on the line. But the referee took charge of that and dispatched two of them."
Halsey has been criticised for failing to spot the severity of the foul by McManaman, although his view was obscured by a Newcastle player.
