They were forced to take evasive action after being targeted by the NBA legend.

Michael Jordan had a pre-game tradition that often left NBA commentators ducking for cover.

The NBA legend is widely viewed as one of the most influential basketball players of all time after winning six NBA Championships with the Chicago Bulls.

Jordan also had a knack for letting others know when it was go time. A showman to say the least.

And one ritual has even been copied since his retirement, further backing up his lasting legacy in the NBA.

Prior to games, the Bulls legend would clap chalk into his hands – often in the vicinity of commentators courtside. Check out the footage below.

This technique is used by many sports stars to enhance their grip, with powerlifters and gymnasts also doing so.

But Jordan would do so every game, right in front of the commentary team, with a running joke soon developing.

Johnny ‘Red’ Kerr – a former NBA All-Star, Chicago native and the first ever Bulls head coach – was among those targeted by Jordan, having moved into broadcast duties in 1970s.

Attempting to crack a smile out of the NBA great, Kerr and his fellow commentators used masks, hats and other eye protection to protect themselves from the chalk.

But after many attempts, umbrellas were pulled out courtside on one occasion, with Jordan failing to contain his laughter. Since then, chalk has become something of a staple with players in the NBA.

Even LeBron James incorporated a signature manoeuvre which fans all around the country began to eat up.

Some even join in pre-game by throwing their hands into the air at the same time.

James has in the past been quizzed on why he does so, without specifically citing Jordan as an influence.

Speaking on the NBA’s official YouTube channel, he said: “I don’t remember the first time I started it but I felt the fans started to embrace it.

“I started to really set my mind and get focused on what was at task when I started to do it. On the road sometimes I get booed, so I love it. At home, they go crazy.

“I don’t know what made me start doing it but it just happens sometimes. Great things just happen sometimes.”
