ATHENS, Ga. (AP) - Two people familiar with the results say Isaiah Crowell and two other Georgia tailbacks were suspended for Saturday's game against New Mexico State after failing drug tests administered last week.

The tests were administered on Wednesday night and the results were confirmed on Tuesday.

The people spoke to The Associated Press on Wednesday on condition of anonymity because Georgia does not release the results of the tests.

According to athletic association policy, student-athletes are suspended for 10 percent of their competitions for first-time violations of the drug tests.

Head coach Mark Richt blasted critics of his decision who questioned the timing of the punishment for a game against a WAC opponent instead of rival Florida.

"We've always had the utmost integrity in everything we do. We have policies in place in our athletic association that we follow to the T. That's the case here and it's been the case since I've been at Georgia," Richt said Wednesday morning on the weekly SEC teleconference.

"People who make comments who don't know probably shouldn't, quite frankly, because they don't know and I'd be able to prove 100 percent they're wrong. But I'm not going to spend the time doing that. The bottom line is we have rules and we follow them to the T and we have the utmost integrity in how we go about our business."

Crowell, a freshman, leads Georgia with 689 yards rushing and four touchdowns. Tailbacks Ken Malcome and Carlton Thomas also were suspended on Tuesday for what was announced as violations of team policy.

ESPN first reported the failed drug test.
