"As a professional athlete, I have been careful about what I put in my body. I took a recommended supplement to combat inflammation. Unfortunately this supplement contained an ingredient that was on the NFL's banned substance list. I take full responsibility and I'm deeply upset with myself for not doing the proper research on this supplement. I want to apologize to my family, the Bears organization, my teammates, and Bears fans. I will work hard to earn back the respect and trust of the Bears nation and look forward to being back on the field."
