The fracas was finally resolved when referee Dowd ordered both managers to the stands.
Both Kinnear and Brown are expected to face heat from the FA, with the former likely to be in serious trouble as he has already been sent off earlier this season.
“I don't know why I was sent off,” Kinnear said in his defence. “We just exchanged words. Nothing else. I'm bemused. It was a harsh decision. He came across and had plenty to say and I answered him.”
Brown branded the incident “unfortunate” saying: “We will just have to see what happens. I was contesting the fact that every time the ball came to Danny Cousin their centre-half came through the back of him.”
Neither manager is a stranger to disciplinary action from the FA this season. Kinnear arrived at Newcastle with an outstanding two-match touchline ban, was warned following an expletive-laden rant at journalists, and was censured after being sent off in a home game against Stoke and calling referee Martin Atkinson ‘Mickey Mouse’ following a 2-1 defeat at Fulham.
Brown was earlier fined for kicking a water bottle in the home defeat against Wigan.
The incident stole the headlines on what was otherwise a fine night for Hull, as they progressed to the fourth round of the FA Cup for the first time in 20 years, courtesy of Cousin’s 82nd minute winner.
The Tigers can now look forward to a home tie against Millwall.
