Stevenage boss Graham Westley has said Chesterfield counterpart John Sheridan should be "ashamed of himself" for claiming Boro players feigned injury.
The sides played seven minutes of injury time in Saturday's 1-1 draw, with Sheridan saying some Stevenage players had "pretended" to be hurt.
But Westley told BBC Three Counties Radio: "What was said in the press at the weekend was a disgrace.
"John Sheridan should be ashamed of himself," he added.
With Stevenage leading 1-0, Sheridan was angered by what he believed were stalling tactics by the away side.
Boro midfielder Ronnie Henry received prolonged attention to an injury - and subsequently missed Tuesday's win at Bournemouth - before Chesterfield equalised deep into added time through Jack Lester.
The game also saw Stevenage midfielder Michael Bostwick dismissed, after he received a second yellow card for a challenge on Mark Allott.
Sheridan told BBC Radio Sheffield: "It was a bad tackle - I'd say the worst tackle in the game. Other than that, people [...] were pretending to be hurt but they weren't hurt.
"I don't know why we had seven minutes because I don't think there was a bad tackle in the game.
"There wasn't a bad injury in the game. There were one or two feigning injury and we'll just leave it at that - we know who they are."
Speaking after Stevenage's 3-1 win over the Cherries on Tuesday, Westley said: "[Sheridan] has hammered Ronnie Henry for going down, but Ronnie missed the game tonight and he was in a bad way on the coach on Saturday night.
"To accuse one of our players of feigning an injury is a disgrace and he should be ashamed."
