Oldham Athletic manager Micky Mellon was shown a straight red card after appearing to headbutt Sheffield Wednesday midfielder Callum Slattery during the FA Cup first-round tie between the two sides.
The League Two Latics were looking to cause a shock against their League One opponents in what was Dave Challinor's first game in charge of Wednesday. Oldham took the lead in the 66th minute through Calum Kavanagh, but Wednesday hit back 11 minutes later when David Kellor-Dunn found the back of the net.
