The Court of Arbitration for Sport says it will rule on tennis player Robert Kendrick's doping ban appeal before the U.S. Open.

Kendrick tested positive for a banned stimulant and is seeking a reduced three-month ban. It would expire before the tournament begins on Aug. 29

CAS will hear Kendrick's case in New York on Aug. 18 after the International Tennis Federation agreed to a fast-track process. The verdict will be issued within days.

Kendrick tested positive for methylhexaneamine at the French Open on May 22.

The ITF banned the 31-year-old American for one year, despite his explanation that he took a capsule to combat jet lag.

Kendrick, whose ranking peaked at No. 69 two years ago, has dropped to 110th.
