LONDON (AP) -- Wheelchair tennis player Ilanit Fridman of Israel has been suspended one month after testing positive for a banned substance that is used to treat asthma.

The 29-year-old player tested positive for terbutaline at the U.S. Open Wheelchair Tennis Championships on Oct. 5 in San Diego, the International Tennis Federation said Thursday.

While Fridman committed a doping offense, the tribunal found no intent to use the drug to enhance performance, which would have carried a two-year ban.

The ITF said Fridman didn't have a "therapeutic use exemption." The ruling comes two days after the ITF suspended American wheelchair player David Buck 31/2 months for a positive cannabis test.
