PRO FOOTBALL DAILY REPORT : NFC : Cowboys’ Holmes Out for a Year?

Defensive back Clayton Holmes may be lost to the Dallas Cowboys for a full year because of violations of the NFL’s substance-abuse policy, the Fort Worth Star-Telegram reported Tuesday.

The NFL announced Friday that Holmes and defensive tackle Leon Lett had been suspended for four games, effective immediately. But a source the newspaper did not identify said the league intends to suspend Holmes for a year.

NFL spokesman Greg Aiello said, “I only know what we announced.”

Cowboy owner Jerry Jones also declined comment. There is no indication that Lett will be suspended for any more than the announced four games, his agent said Monday.
