Given the current climate in the AFL regarding the bump, Collingwood midfielder Tarkyn Lockyer admits Chris Bryan is playing "Russian roulette".

Bryan will find out on Monday whether the AFL match review panel charges him for his contact with Geelong midfielder Joel Selwood during the NAB Cup grand final.

The Magpie ruckman ran into Selwood early in the second quarter on Friday night at Etihad Stadium.

Selwood suffered no ill-effects - indeed, the young Cat was in the midst of a purple patch during the game that would earn him the Michael Tuck Medal as best afield in the pre-season grand final.

"To be honest, I can't recall the incident, so I can't really comment," Lockyer said.

"The only thing that I do know is if you bump these days, you're playing Russian roulette, so hopefully we're alright."

Already this pre-season, Collingwood captain Nick Maxwell has become the first player to successfully appeal against a tribunal verdict under the current system, when he challenged his bumping suspension.

He received a four-week penalty at the tribunal for rough conduct, but the appeal board ruled in Maxwell's favour and that forced the AFL to rewrite their laws regarding head-high bumps.

The Maxwell case generated considerable debate about the future of the bump in the game.

Last week, Port Adelaide coach Mark Williams revealed he had told his players not to bump opponents because it is now such a grey area in the game.

Meanwhile, the match review panel will also consider at least two other incidents from the weekend's practice matches.

Carlton forward Simon Wiggins was booked for rough conduct against Fremantle rookie Greg Broughton during Saturday's NAB Challenge game in Bunbury.

Melbourne midfielder Clint Bartram was reported for front-on contact with Western Bulldogs utility Daniel Giansiracusa on Saturday at Casey Fields.
