Philadelphia Eagles linebacker Jake Knott was suspended without pay for the first four games for violating the NFL performance-enhancing drug policy.
"We're very disappointed to learn of his suspension," the team said in a statement. "We have spoken to Jake and he is fully aware of the mistake he made and owned it. The key for him, however, is to learn from that mistake and move forward with his preparation for the 2014 season."
Knott said his suspension stems from unknowingly ingested a banned substance.
"Several weeks ago, I was shocked to learn that I tested positive for a stimulant that is banned by the NFL," Knott said. "I have never knowingly ingested a banned substance, but like most players, I take nutritional supplements. Unfortunately, I now know that supplements are not regulated and thus may contain things that are not listed on the label. The NFL policy is very strict, so I have chosen to take immediate responsibility.
"I look forward to participating in team workouts, training camp and the pre-season with my team. During the suspension, I will work extremely hard to stay in top football shape and be ready to contribute immediately upon my return. I sincerely apologize to my teammates, coaches, my family and fans for the impact of my mistake on the team."
