Collingwood youngster Taylor Adams overstepped the mark and will cop his two-match ban for kneeing Port Adelaide’s Justin Westhoff, coach Nathan Buckley says.

The 21-year-old was one of four players offered suspensions on a busy day for the match review panel after he repeatedly dropped a knee into Westhoff’s head while the Power big man was pinned to the ground during the Pies’ narrow loss at Adelaide Oval.

“I had a chat to Tay afterwards … we don’t want to be a side that goes over the edge but we want to play on the edge,” Buckley told Fox Footy.

“Taylor’s an aggressive player but he’s let himself and his team down.

“He’s growing as a player and as a young leader amongst our group. He’s rounding off some rough edges as he goes and he’s still got a few more to round off.

“He’s brilliant but we’re going to miss him for two weeks and that hurts us.”

In the major MRP storylines, Geelong skipper Joel Selwood was slapped with a one-match ban, while Fremantle star Nat Fyfe remained in the running for the Brownlow Medal after escaping with a fine.

Selwood was charged with engaging in rough conduct for his chicken-wing tackle on North Melbourne’s Sam Wright, which the MRP deemed intentional conduct with medium impact to the body.

Selwood risks a two-week suspension if he contests the sanction or can miss this week’s match against the Western Bulldogs if he enters an early guilty plea.

Fyfe was also charged with rough conduct after his forearm made contact with Taylor Duryea’s face in the Dockers’ heavy loss to the Hawks in Launceston.

With a suspension, the raging Brownlow Medal favourite would have been ineligible to win the game’s highest honour, as he was last year when he finished second in the count.

Former Hawthorn skipper Sam Mitchell courted controversy when he collided with Fyfe in similar fashion to an incident involving Adelaide’s Taylor Walker earlier this season.

Mitchell escaped sanction for his knee to Walker’s thigh but the MRP took a dim view of Sunday’s action, charging the Hawk with kneeing Fyfe, which attracts a $1000 fine with an early plea.

Richmond’s Tyrone Vickery was charged with engaging in rough conduct, and offered a two-game ban, after his high block caught Carlton defender Michael Jamison unawares and resulted in him being subbed out.

North Melbourne forward Drew Petrie was the only other player to be offered a suspension after the big Roo was charged with striking Geelong’s Andrew Mackie.

He can accept a one-game ban or risk two if he challenges.
