RICKY BURNS has become only the second Scot to be crowned world champion at two different weights.

Mexican ring legend Juan Manuel Marquez as expected yesterday relinquished his WBO lightweight title to pursue a fourth super fight with Manny Pacquiao.

And that meant Burns, who was Marquez's mandatory challenger and the WBO's Interim title holder after his November win over Michael Katsidis, was elevated to full world champion status.

The 28-year-old is now world title holder at a second weight after previously having ruled at super-featherweight before vacating to move up to nine stone nine.

And he emulates Irvine's Paul Weir who held the WBO straw- weight title in 1993 before claiming the WBO light-flyweight belt in 1994.

Now the Coatbridge fighter has vowed to make the first defence of his new title against Namibia's Paulus Moses at Braehead Arena on March 10, a night to remember. Burns said: "When I got the news that Marquez had vacated and I was the new champion I could not believe it.

"It is hard to put into words, but what I can promise the fans who come to see me at Braehead on March 10 is a great night.

"There is no way I am going into that one having been handed the title outside of the ring only to lose it inside at my first defence.

"I new it was only a matter of time before Marquez vacated to fight Pacquiao again, but it has been frustrating waiting for him to make that call. But he has done the right thing and fair play to him.

"Now it is up to me to produce a performance worthy of a two-weight world champion on March 10."

"To have my first fight in Scotland in three outings and walk into the ring with that world title around my waist to meet Moses is a moment I can't wait for. There is no way I will be leaving Braehead without it."
