Newcastle have been hit with fresh controversy, which saw their under 21's coach Willie Donachie resign after being accused of clashing with defender Remie Streete as reported by the Daily Mirror.
Donachie, the former Scotland International, was told to stay away from the club and told he would potentially be facing the sack.
But late on Thursday night the club announced that he had quit.
The clash between the two was reported after the Magpies under-21 side suffered a 2-0 away defeat to rivals Sunderland last Monday night.
Streete had given away a penalty and there was a toe to toe row with Donachie, who is said to have lashed out and connected with the player.
Shocked team members piled in to seperate the pair and Streete stormed out of the dressing room.
The incident happened a couple of hours after Director of Football Joe Kinnear was sacked in an unrelated development.
Donachie's resignation capped a turbulent week for the North East club, which included Alan Pardew's Premier League side losing at home to Sunderland.
