Olympic boxing champ's Vegas fight off

The dual Olympic gold medalist was due to fight Vlajk in a junior bantamweight bout on the Canelo Alvarez vs. Gennady Golovkin undercard, but the bout was abandoned just before the fighters were due in the ring.

Briton Nicola Adams' fight against Alexandra Vlajk in Las Vegas was called off after a problem with her opponent's pre-fight blood test.

"I'm devastated that I'm not boxing tonight, due to a problem with my opponent, thank you everyone for your support and kind messages", Adams wrote on Twitter.

The Las Vegas fight on a huge pay-per-view event would have been Adams's most high profile fight as a professional and increased her exposure in the U.S. and internationally.

The 34-year-old made her professional debut in April, out-pointing Virginia Noemi Carcamo and then made her Leeds homecoming in May, stopping Maryan Salazar in the third.

Earlier in the week she had said: 'I don't know if we've ever had women on the undercard of such a big event before, or in Vegas.
