North Melbourne AFL forward Lindsay Thomas faces a two-match suspension for the incident which broke Sydney youngster Gary Rohan’s leg.

Thomas was hit with the penalty by the AFL match review panel on Monday for rough conduct.

In a ruling sure to incite debate, the panel deemed Thomas’ sliding motion into Rohan illegal, and labelled its impact severe.

Rohan will miss the rest of the season after the sickening leg break in Sunday’s match at the SCG, which the Swans won comfortably.

Thomas can accept a two-match ban if he pleads guilty, otherwise he risks having the suspension increased to three weeks if he takes the matter to the tribunal and loses.

Geelong’s Steve Johnson and St Kilda forward Justin Koschitzke face suspension for their clubs’ next matches after falling foul of the match review panel.

Johnson faces a one-match ban for rough conduct over an incident involving Richmond’s Chris Newman in the Cats’ 10-point win.

He can also escape with a reprimand over a tripping charge, and would only serve a one-match ban on both counts should he plead guilty.

Koschitzke will miss his side’s clash with Melbourne this weekend should he plead guilty to striking ex-teammate Zac Dawson in the Saints’ loss to Fremantle and accept a one-match suspension.

Geelong ruckman Trent West and Sydney defender Ted Richards can accept reprimands – West for rough conduct and Richards for striking.

But Essendon midfielder Sam Lonergan escaped penalty for the tackle which broke Carlton onballer Andrew Carrazzo’s shoulder.

Richmond’s Reece Conca was also cleared of high contact on Geelong’s Allen Christensen.

But Greater Western Sydney defender Chad Cornes and Adelaide’s Matthew Jaensch were fined for wrestling.

Cornes can accept an $1800 fine and Jaensch $900 if they make early guilty pleas.
