Chinese Taipei baseball player Zhang Tai-shan's doping case was not within the Olympic doping control period, said the International Olympic Committee (IOC) on Thursday.

The International Amateur Baseball Federation (IBAF) said in an earlier statement that "The IBAF has been advised of a possible anti-doping rule violation by a player from the Chinese Taipei team. As a result the player Tai-Shan Chang has been provisionally suspended pending the analysis of the B sample and a formal hearing."

Although the doping case was revealed during the Beijing Olympic Games, IOC director of communications Giselle Davies said it was not under the control of the IOC.

"It is not a test by the IOC in the Games-time period," she told a daily press briefing at the Main Press Center.

It was reported that Zhang failed the test carried out by the World Anti-Doping Agency before the Games.

So far, there is only one doping case at the Games that Spanish cyclist Maria Isabel Moreno was found using banned substance EPO or erythropoietin.

The 27-year-old , entered for individual time trial, was tested on July 31 in the Olympic Village and left China later that day before learning the result.

The IOC pledged to make the Beijing Games a "clean" one and planned a historic-high 4,500 tests through the Olympic period, which started on July 27 through to the closing of the Games on August 24. It is a 25 percent increase from the 3,600 tests in Athens where 26 doping cases were reported.
