Caster Semenya joins South African football team JVW

Two-time Olympic 800m gold medallist Caster Semenya has joined a South African women's football team.

The 28-year-old is unable to compete without taking testosterone-reducing drugs following a rule change by the IAAF, athletics' governing body.

It means she cannot defend her 800m World Championship title in Doha this month - though she is fighting the rule change through the courts.

She is now training with Gauteng-based women's football club JVW.

The three-time world champion, who announced in July that she would not be defending her 800m world title, cannot starting playing for JVW until the 2020 season, having joined outside the South African transfer window.

"I am looking forward to this new journey, I appreciate the love and support I already get from the team," Semenya told the club website.

JVW FC was formed in 2013 by current South Africa Women's captain, Janine van Wyk, aiming to "identify, develop, improve and expose" female footballers.

The club is one of the top sides in the league for Gauteng province - the main women's football league in South Africa is split into nine provincial competitions.

Club founder Van Wyk said she was "absolutely honoured" that Semenya had chosen JVW "as the club where she would like to start showcasing her football skills".

She told the BBC: "She is signing with the team to play in 2020 as the transfer window is currently closed for this season. She is part of the team."

Semenya is not the first athlete to transfer to football - after retiring in 2017, Usain Bolt joined Norwegian side Stromsgodset before signing for Australian side Central Coast Mariners, but he left after eight weeks at the club.

She is also following in the footsteps of her onetime coach Maria Mutola - who also turned to football after athletics.

The IAAF introduced its rule change because it argues female athletes with differences of sexual development (DSD) - such as Semenya - have "a competitive advantage".

Athletes must either take testosterone-reducing medication in order to compete in track events from 400m to the mile or change to another distance.
