Roberts, who had only been on the field for a couple minutes, lunged at Given in injury time and was seen involved in a row with Barron as the teams left the field.
Barron's counterpart Bobby Mimms also got involved, but the United goalkeeping coach was unmoved and he stood his corner.
And he told the Evening Chronicle: "I didn't think it was right the way Jason Roberts went in on Shay, and there was a risk that he could have been injured.
"I told him he had every right to go for the ball, but I asked him why he did not try and head it because it was up in the air.
"He caught Shay and we were worried for a while because we all know what happened at West Ham a couple of years ago.
"Fortunately, Shay is OK, apart from being very sore, and he has a couple of huge stud marks on his hip.
"But when one or two of their staff became involved after the game I had my say, and I make no apologies for sticking up for Shay because that's what we are doing for each other at the club at the moment."
