Injured batsmen should be prevented from using runners, Australia's retiring captain Steve Waugh said.
Waugh, who once scored a century against England while batting on one leg, said the practice of injured batsman calling for runners should be abolished from the game.
"I don't think you should have runners as a batsman, bowlers, when they get injured, don't have any help," Waugh told reporters on Thursday.
"I think batsmen if they get injured, they've got to play their shots or get out.
"There's a lot of confusion when runners get on the field, and over whether the guy is actually injured."
Waugh, who is retiring from international cricket after the final Test against India starting on Friday, made an unbeaten 157 against England at the Oval in 2001 when he batted injured.
The Australian skipper had torn his calf muscle in an earlier match but made it back for the last game of the series after weeks of intensive physiotherapy.
He injured the calf again during the Test but decided to battle on in pain.
Asked by reporters what other rules needed changing, Waugh nominated the scrapping of leg byes: "I don't see any reason why you should get runs when you miss the ball," he explained.
