Lutalo Muhammad could face Aaron Cook in December for the first time since being controversially selected ahead of his fellow Briton for London 2012.
Despite Cook being ranked world number one at the time,
GB Taekwondo selected Muhammad,
who won Olympic bronze.
The pair have both been named in the -80kg division for the Grand Prix event in Manchester from 3-15 December.
Since London 2012 Muhammad has competed in the -87kg category, losing in the
2013 World Championship quarter-finals.
However, he returned to winning ways
with victory in that category
at the National Taekwondo Championships in September.
The -87kg division is not an Olympic category which means Muhammad had to decide whether to compete in +87kg or -80kg in the 2014 Rio Games, hence him dropping down to -80kg.
Friday 13th December
Bianca Walkden +67kg
Saturday 14th December
Lutalo Muhammad & Aaron Cook -80kg
Sunday 15th December
Jade Jones -57kg
Martin Stamper -68kg
Michael Harvey -68kg
Cook, who has opted to
compete for the Isle of Man
after his Olympic snub, has spent the past couple of months
building up his ranking points in South America
after being eliminated in the opening round of the 2013 World Championships.
GB Taekwondo has also confirmed that Olympic champion Jade Jones will compete in the -57kg division in Manchester.
"We're now just eight weeks away from the world's first ever Taekwondo Grand Prix and I'm delighted to be a part of the GB team confirmed to compete at the event," she said.
"The support at the Games was unforgettable and I hope that when I step on the mat on 15 December that the crowd can recreate that atmosphere and support."
Other British fighters in the main draw include European champion Michael Harvey and London Olympian Martin Stamper (both -68kg), and Bianca Walkden in the +67kg class.
As the host nation Britain will also be allowed eight further wildcard places, which will be revealed in mid-November.
The event will see 250 of the world's top competitors across eight different weight categories come together to battle it out for vital qualification points ahead of the Rio 2016 Olympics.
All 16 of the 2013 World Championship gold medallists and all eight gold medallists from the 2012 Olympics are expected to take part.
