Wayne Rooney's match-winning double in Manchester United's 2-0 victory against Sunderland was overshadowed by a case of mistaken identity.
The England captain opened the scoring from the penalty spot in the 66th minute after Falcao had been pulled back by John O'Shea.
But, instead of sending off the Irishman, referee Roger East showed a red card to his fellow former United defender Wes Brown.
East later told the body responsible for officiating standards in English football it was not a case of mistaken identity when he sent off Brown.
Rooney added a second six minutes from time, and the win was enough to lift United above Arsenal and back into third in the Barclays Premier League table ahead of the Gunners' clash with Everton on Sunday.
In the early game, former West Ham boss Alan Pardew enjoyed his return to Upton Park as his Crystal Palace side came away with a 3-1 victory.
Glenn Murray gave the visitors the lead four minutes before half-time, although his header certainly would not have found the net had Aaron Cresswell not made a horrendous mess of an attempted clearance.

A header from Scott Dann six minutes after the break doubled Palace's lead and Murray then headed in a third before his afternoon ended early with a second yellow card seeing the forward dismissed.
Enner Valencia pulled one back for West Ham 14 minutes from time but that was as good as it got for Sam Allardyce's stuttering side.
At the bottom of the table, West Brom pulled further clear of the relegation zone with a 1-0 victory over Southampton thanks to Saido Berahino's goal in only the second minute.
Along with Sunderland, there were defeats for three other members of the bottom six, all of them 1-0.
Aston Villa lost to Newcastle at St James' Park.
A Kieran Trippier own goal condemned Burnley to a home loss against Swansea, while Peter Crouch equalled Alan Shearer's Premier League record of 46 headed goals seconds after coming on as a substitute as Stoke needed only one goal to beat Hull.
