Lions DT Nick Fairley, arrested twice since April, apologized Friday on his Facebook page.
Fairley, charged with DUI and eluding police in May and cited for marijuana possession the previous month, wrote:
"I want to personally apologize to my fans, teammates and the Detroit Lions organization for bringing this unwanted attention to our team. I recognize my actions were inexcusable and I personally need to uphold the expected standard of behavior of a professional athlete. I do not take for granted this opportunity and feel blessed everyday to play in the NFL.
"At this time, I am fully cooperating with the Mobile, Ala. Police Department. I am now focused on moving forward and committing my focus to football. I would like to thank everyone for your concern and understanding."
Fairley was the Lions' first-round pick in 2011. Hampered by a foot injury, Fairley notched 15 tackles in 10 games as a rookie.
Fairley would face NFL discipline were either charge to result in a finding or plea of guilt.
