Botha's cortisone use a concern

Joseph Parker's trainer, Kevin Barry, says Francois Botha's recent admission to using cortisone is a concern after he tested positive for nandrolone before beating Axel Schulz to win the IBF Heavyweight Championship.

Both Botha and Parker underwent urine and blood tests today, and although Botha's urine test came up negative, the blood test results won't be available for another 10 days.
