Mandatory world title challenger Anthony Crolla from Manchester was in another gruelling war this past weekend and his post-fight urine sample for his post-fight drug test showed just what fighters can go through at times.

Boxing can often be a brutal sport and for the brave few that step in the ring physical injury is always a risk.

Former world champion Anthony Crolla’s fans follow him for this constant willingness to go to war and fight the very best.

This past weekend he scored a points win on the Oleksandr Usyk vs Tony Bellew card in Manchester which now puts him in line for a shot against pound for pound supremo Vasyl Lomachenko next up.

After the fight Crolla posted this discolored picture of his urine sample:
