Bolton boss Gary Megson has accused Hull City of trying to get Kevin Davies booked during the 1-1 draw at the Reebok.
Megson claims a member of the Tigers' backroom staff went into referee Peter Walton's room at half-time to complain about Davies.
After the break, Davies was involved in the major flashpoint in the 1-1 draw when his tackle on Andy Dawson in front of the dugouts provoked a furious reaction from the Hull bench.
Tigers assistant boss Brian Horton had to be restrained by a police officer but Megson claims the protests had started long before then.
"I was getting a little bit annoyed with what was going on," Megson told The Bolton News.
"I know a member of Hull's staff went into the referee's room and was moaning about Kevin Davies.
"He's as honest as the day is long and I don't take kindly to any bench, not just Hull's, trying to get him booked to gain an advantage."
Davies was also not impressed by the conduct of Hull's backroom staff.
"The way their bench over-reacted was disappointing," he said.
"I'd heard they had been on to the ref at half-time saying I was leading with the elbow.
"That shows how desperate they were."
