Lothersdale's Double Paralympic champion Danielle Brown has been ruled out of future international Para-Archery events after a change in the sport’s classification rules.

It means she will be unable to defend her Paralympic title in Rio in 2016.

Brown shoots while seated on a stool due to a condition that causes chronic pain in her feet.

However, in a statement, World Archery said: “The Paralympic Games and World Archery Para Championships should not be for anyone who has a physical disability but for those athletes with a disability where the disability has a direct and important impact on the archery performance.”

Brown won compound gold in both Beijing and London but she has also competed for GB in able-bodied competition and won compound team gold for England at the 2010 Commonwealth Games in Delhi.

Earlier this week, she won two silver medals at the Para-Archery World Championships in Bangkok, narrowly failing to claim her fourth individual world title in a row.
