A manager who oversaw an FA Cup upset was sent off for headbutting a player on the opposing side.
Micky Mellon was no longer on the touchline to see his Oldham Athletic side complete an extra-time victory against Sheffield Wednesday because he had been red carded.
In the 84th minute, manager Mellon pushed his head towards Wednesday midfielder Callum Slattery and was given his marching orders. Slattery was booked after a touchline fracas was calmed down.
League Two Oldham eventually dumped League One Wednesday out of the famous cup competition after a 2-1 win, with Will Sutton's 110th-minute winner.

Oldham assistant manager Gary Brabin, on press duty after Mellon's red card, said: "It was a proper cup tie and we are delighted to come out winners.
"When you look back on the match, I think we were deserved winners.
"We have been doing well recently and today reinforced that with a good performance and a good result."
After an uneventful opening two thirds of the match, it suddenly exploded into life when Calum Kavanagh put Oldham ahead in the 66th minute with his sixth goal of the season.
Wrexham loanee and former Oldham forward Davis Keillor-Dunn equalised 10 minutes later with his fifth of the campaign before Sutton had the final word.
It was not the start Dave Challinor dreamt of from his first match as Owls manager.
He said: "I am really frustrated and disappointed not to have won.
"The first half was like a testimonial in being so slow -- not like I want a team of mine to be.
"The second half was a whole lot better, but we conceded a goal during our best spell of the match.
"The substitutions changed the dynamics of the game -- it would have been better if we had started that way.
"There is plenty of work to do -- change won't happen overnight but hopefully you saw some structure."
