OXNARD, Calif. - Cowboys defensive end Damontre Moore apologized Saturday, the day after the NFL announced he is suspended for two games for violation of the NFL's substance abuse policy.

Moore was arrested in December on suspicion of DWI while playing for the Seattle Seahawks. The Cowboys knew league discipline was possible when they signed him this offseason and stand by Moore.

"I made my bed and I've got to lie it in," Moore said. "I just wanted to apologize to the Cowboys organization and the fans for my past even following me. I also want to show them by coming here and working hard each and every day that I'm here to...make the best of this opportunity."

Moore will be eligible to return to the Cowboys' active roster on Monday, September 18 following the team's September 17 game against the Denver Broncos.

Moore is eligible to participate in all preseason practices and games.

Moore has 10 career sacks entering his fifth season, but is looking to put a troubled past behind him as he's hopped from the New York Giants to Miami to Oakland before landing at home in Dallas.
