49er: 'No sympathy' for NFL test violators

Bruce Irvin apologized and claimed "full responsibility" for incurring a four-game NFL suspension, announcing he would not appeal the punishment.

The second-year Seattle Seahawks defensive end did not ask for sympathy, and he's not getting any from San Francisco 49ers safety Craig Dahl.

"I have no sympathy for violators of NFL drug test," reads a tweet from Dahl's verified Twitter account. "It's easy to know what goes in your body. If this was another sport what would happen?"

Irvin will miss a Week 2 game against Dahl's 49ers.

"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," Irvin said in a statement released by the team. "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."
