Five TCU football players tested positive for marijuana and failed a Feb. 1 drug test initiated by coach Gary Patterson, a source told the Star-Telegram. Another 11 had trace amounts within the margin of error, the source said.
Marijuana was the only drug detected. Eighty-six players were clear.
Patterson ordered the tests after a recruit complained of drug use by players and turned down the Horned Frogs' scholarship offer, sources have said.
On Wednesday, arrest warrant affidavits quoted players as saying 60 to 82 players likely failed the test.

It's unknown whether the four players arrested in Wednesday's drug bust -- Tanner Brock, D.J. Yendrey, Devin Johnson, and Ty Horn -- were among those who tested positive, but Brock told an undercover officer that he failed the test, according to the arrest documents.
A second source, a former player, said that the numbers quoted in the affidavits were exaggerated.
"There was definitely a small group of guys using weed but nothing more than that," he said.
"I think weed in general is prevalent on college campuses. A lot of students look at it just like alcohol."
