Notre Dame wide receiver DaVaris Daniels has maintained he writes his own papers and likely relayed that message to Notre Dame officials in an interview this week, a source close to Daniels told CBSSports.com.

Daniels, the team's leading returning receiver, is one of four Irish players in the center of an academic investigation conducted by the school. Cornerback KeiVarae Russell, defensive end Ishaq Williams and linebacker Kendall Moore are the others.

"He said he wrote all his papers," the source said. "They asked him about some emails and papers that he wrote. He told them what he knew."

The school says it found evidence students submitted papers and homework that had been written for them. The compliance office in athletics learned of the detection on July 29, the school says.
