VIENNA (AP) -- Austria's Daniel Koellerer, the first player banned for life for attempting to fix tennis matches, is fighting his suspension on the national level.
The Austrian tennis federation banned him from all national tournaments and competitions after he was convicted last week by the international Tennis Integrity Unit.
Koellerer's manager Manfred Nareyka says Koellerer can still appeal the verdict until June 20.
The former 55th-ranked Koellerer is hoping to play on Austria's national team competition, which started last weekend.
Koellerer was found guilty of three violations of the sport's anti-corruption rules, including "contriving or attempting to contrive the outcome of an event." The violations occurred between October 2009 and July 2010.
