Brogan was found guilty of bumping over Andrew Lovett at quarter-time at AAMI Stadium on Sunday, although he had a win of sorts when the three-man jury downgraded the suspension from two games to one.

The jury lowered the conduct element from intentional to negligent, but the Power will be without their big man for Sunday's game against West Coast.

In the other case heard Tuesday night, Geelong forward Steve Johnson was found not guilty of attempting to strike Hawthorn's Luke Hodge at the MCG last Friday night.

Brogan admitted he bumped into Lovett's back as the pair moved towards their huddles at quarter-time, because he was determined not to move off his line as a show of strength.

But he gained little support from Lovett and umpire Dean Margetts, who both said the contact forced the Bomber speedster to the ground and was unnecessary.

Lovett said he did not expect to be bumped from behind and that players should be "civilised" when walking towards huddles at breaks in play.

"It surprised me, it was the end of the quarter and I wouldn't expect to get hit by anybody," he said.

Margetts said the contact was forceful enough to knock Lovett down, and had no doubt Brogan acted unreasonably.

"It's one thing to show strength face to face, but another when a player isn't looking," he said.

Brogan was adamant Lovett "milked" the incident, and told the tribunal Lovett had told him not to worry about the matter after the game, which Port won comfortably.

After the verdict was handed down, Port argued for the jury to reduce the penalty even further because of compelling circumstances, that there was no footage of the incident, it happened at quarter-time and there were inconsistencies among the witnesses' evidence.

The jury rejected that submission.

Lovett's evidence provides for a spicy reception when Port and Essendon clash later in the year, and Bombers coach Matthew Knights on Tuesday warned his star to expect more physical attention this season.

Port appeared to target Lovett as they asserted themselves, and Knights said he noticed some specific attention.

"It's a great experience for Andrew because there's been a chequered past, he's got his act together and he looks like he's going to have a good season," he said.

"He's got to expect that."

Lovett was one of his side's best against Port after the Bombers nearly traded him last year, following two club-imposed suspensions in 2008.

Johnson argued that he was trying to fend off Hodge from tackling him during the second quarter of the grand final rematch, and the tribunal took his word.

Johnson would have been reprimanded and had 60 demerit points put alongside his name had he been found guilty, but he retains his clean record.

Earlier on Tuesday, Hawthorn ruck Simon Taylor accepted a two-game suspension for misconduct, kneeing Geelong's Joel Selwood in the face as the Cat lay on the MCG turf last Friday night.

Carlton's Kade Simpson accepted a reprimand for making a forceful, front-on contact on Richmond's Daniel Jackson last Thursday night.

Sydney star Adam Goodes will be docked $1,950 for making negligent contact with an umpire last Saturday night at Etihad Stadium.
