Greater Western Sydney coach Kevin Sheedy has slammed the AFL for contemplating a mid-season rule change on sliding.
The AFL is ready to alter its stance on sliding if a new crackdown on the approach proves unsuccessful.
Umpires have been instructed to pay more free kicks in hope of preventing injuries caused by players sliding along the ground in contested situations.
Players who now slide into a contest with their feet or knees and make contact with an opponent below the knees will be penalised.
The warning comes after Sydney youngster Gary Rohan suffered a broken leg in a collision with North Melbourne's Lindsay Thomas, who was cleared by the tribunal after being charged by the match review panel, while Fremantle's Greg Broughton was also cleared this week after being cited for a slide on Gold Coast's David Swallow.
But Sheedy, a three-time premiership player with Richmond and four-time premiership coach of Essendon, said the AFL is out of line for proposing change during the season.
"I don't believe that we should be making rules on the run," a somewhat testy Sheedy told Fox Footy's AFL 360 program on Thursday night.
"You put it in at the start of the year. You do not bring rules in during the year.
"If you have a car accident does that mean we have to change every stop light and roundabout in the whole of Australia?
"Investigate all the concerns that are in the game and then sit down as a panel of experts and make out the new rules.
"It's about making the rules that are going to make this game of AFL the most exciting game in the world.
"Sit down and get it right but don't make rules on the run."
The Giants face Gold Coast at Manuka Oval in Canberra on Sunday, with Sheedy's side searching for their maiden AFL victory.
