Preston North End manager Simon Grayson has described Eoin Doyle and Jermaine Beckford as an "absolute embarrassment" after they were sent off for fighting each other on Saturday.
The two strikers squared up near the end of their side's 2-1 loss at Sheffield Wednesday as they chased an equaliser, and are likely to receive three-match bans for violent conduct.
"I've been in the game for 30 years playing and managing and I've never been involved with anything like that," Grayson told BBC Sport.
"I spoke to them in the dressing room and they were apologetic, but that doesn't wash with me, something like that should never happen in the professional game.
"It's an absolute embarrassment. I stick up for my players at every club I've been at... but I can't stick up for either of those players."
Preston currently occupy 14th place in the Championship table.
