Oxford United manager Brian Talbot has slammed defender Jon Ashton for his two dreadful errors against Stockport County.
The U's late 2-1 defeat at resurgent Stockport saw The Hatters pull away from the drop zone while the visitors are just a point above the bottom two.
Ashton gifted Tes Bramble the opener at Edgeley Park with a weak backpass, although Tim Sills did manage to level for Oxford on the hour.
However, Ashton produced a reckless challenge on Bramble three minutes from time to hand County a penalty, which substitute Adam Le Fondre converted to hand the hosts all three points.
Talbot was bitterly disappointed with Ashton's performance, and was also unhappy at the defender for not apologising to his team-mates after the game.
"It was suicidal defending by Jon Ashton," said Talbot.
"After the game I left it for five minutes to see if he apologised to the lads.
"He didn't, and that disappoints me. The tackle and why he did it has no explanation."
Meanwhile, Oxford have extended the loan of defender Warren Goodhind from League Two rivals Rochdale.
The South African-born player initially joined The U's on a month-long loan deal and has now agreed to see out the season at The Kassam Stadium.
