SUSPENDED Melbourne midfielder Jack Trengove has pleaded for the match review panel to be consistent in future rulings on tackles similar to that which earned him a three-week ban.

Trengove pinned Adelaide midfielder Patrick Dangerfield's arm in a tackle, leaving the Crow unable to protect his head when he fell to the ground.

Dangerfield immediately left the field with concussion and was ruled out for the remainder of the round seven clash.

Melbourne challenged the controversial suspension at the Tribunal and Appeals Board but failed to have the charge overturned.

After missing his first match at the weekend, Trengove was shown a series of tackles from Adelaide and Gold Coast's round eight clash on AFL Central, which showcased similar technique the 19-year-old had applied a week earlier.

Highlights of the game showed Crow Kurt Tippet pinning the arms of Gold Coast ruckman Zac Smith and slinging him to the ground, while Suns defender Danny Stanley laid two similar tackles where his opponent was slung to the side.

Fortunately for Tippet and Stanley none of the players they tackled hit their head on the ground.

"It's a hard one because nobody really got concussed there, so there are slight differences," Trengove told AFL Central.

"All I sort of ask for, considering what I've been through, is consistency in the system.

"I suppose if there are tackles similar to mine in the future then you hope they get the same punishment but I'm not going to point the finger and try and compare them too much."

Trengove received a lot of support from the football fraternity in the wake of his suspension with former Hawthorn skipper Sam Mitchell and Demons' coach Dean Bailey backing the 19-year-old's tackling technique.

And the number two pick in the 2009 NAB AFL Draft maintained he wouldn't be changing the way he tackles any time soon.

"You don't intend to try and hit your opponent's head on the ground or anything like that, it's just a bit of luck," Trengove said.

"As I said during the week, it was an accident and I really didn't mean it so hopefully in future tackles heads won't hit the ground but I think I'll still tackle the same way."

Dangerfield recovered well from his head clash and was cleared by medical staff to take part in the Crows game against the Suns, and it was clear from his performance that there were no lingering effects of concussion.

The 21-year-old kicked a career-best six goals and had 23 disposals for the day but admitted he was disappointed with Trengove's three-game ban.

"I was pretty disappointed with it [the match review panel's decision], to be honest," Dangerfield said.

"I can't really remember the incident itself, but looking back on the replay I thought it was within the rules of play.

"It's disappointing for Jack and I feel for him that he can't play for the next three weeks."

While Dangerfield enjoyed a return to form, Trengove watched helplessly from the stands on Saturday as his teammates struggled against North Melbourne, but he will be doing his best to make up for his absence when he returns in round 11.

"Nobody likes to sit and watch your team when you could be out there playing so it was pretty hard especially in that second half when the game wasn't quite going our way," he said.

"It's been pretty full on [the last week] but now that we've got the three-weeks, we just have to move on and do my best to be in good condition when I get back."
