The Seahawks will be lacking a significant piece to their defensive for the first four games of the 2013 season thanks to a suspension issued to Bruce Irvin by the NFL.

Irvin has been suspended without pay for violating the league’s policy on performance enhancing drugs.

Irvin released a statement saying:

“I want to apologize to my teammates, coaches and Seahawks fans for making a mistake when I took a substance that is prohibited in the NFL without a medical exemption. I am extremely disappointed in the poor judgment I showed and take full responsibility for my actions. I will not appeal the discipline and instead will focus my energy on preparing for the season so I can begin earning your trust and respect again. I look forward to contributing to the team the moment I return.”

According to a release issued by the team, Irvin will be eligible to return to the Seahawks’ active roster on Monday, September 30 following the team’s September 29 game against the Houston Texans.

Irvin is eligible to participate in all offseason and preseason practices and games.
