Red Bull's Mark Webber says Romain Grosjean should be prepared to run for the hills should he spark another first-lap incident.
Webber and Grosjean will line up in seventh and eighth for Sunday's Singapore Grand Prix as the Lotus driver returns to action after a one-race ban.
Grosjean was suspended from the last grand prix in Italy after sparking a first-corner pile-up in Belgium that took himself and three other drivers out of the race.
That was just the latest in a string of incidents involving the Frenchman this season, and when asked if he was comfortable sharing the same row as Grosjean, Webber said with a smile: "Yeah, he's okay. He knows I've a good right hook on me so he will stay away from me.
"But he better put his sneakers on if he hits me."
Although under investigation by the stewards on two fronts following qualifying, Webber escaped with nothing more than a reprimand.
Marussia's Timo Glock complained he was blocked by the Australian in the first session, but the stewards took no action, while in Q3 Webber twice left the circuit on his in-lap for which he could offer no justifiable reason, earning him a rap over the knuckles.
With his title hopes fading after a poor run during which he has scored just 16 points from the last four races, Webber can only hope for the best tomorrow.
"It was a tough hour (of qualifying) to be honest," said Webber.
"We're scratching our heads because it's not like we didn't get the maximum out of the car.
"Ultimately we're disappointed with the result. Sometimes you don't like the medicine but you have to drink it. That's the way it is.
"But it's a long GP, plenty of strategy involved and anything can happen."
