Soccer-AFC bans Brazilian striker Jaja for four years over doping violation

A Brazilian footballer playing for Thai side Chiangrai United has been handed a four-year ban for doping after failing a test at an AFC Champions League match, officials said Tuesday.

Jaja Coelho was found guilty of breaking anti-doping rules at his club's group stage game against Australia's Melbourne Victory in November, the Asian Football Confederation (AFC) said.

A banned substance was found in the striker's urine sample, they said, without giving further details.

Chiangrai, known as "The Beetles", and Melbourne drew the game 2-2.

The Thai side did not advance past the group stage of Asia's premier club tournament last year, while Melbourne went out in the knockout round to South Korea's Ulsan Hyundai.
