Perhaps there is more to the smoothies that Chip Kelly serves after practice.

Kidding.

The Eagles announced that linebacker Jake Knott will be suspended without pay for the first five games of the season for violating the performance enhancing drug policy.

Knott is eligible to participate in off season workouts and even preseason games, but it's unlikely due to his status on the team. The Eagles will likely look to solidify the linebacker position in next months draft.

Knott, 23, played his collegiate football at Iowa State before going undrafted in 2013 and signing with the Eagles shortly afterwards.

A statement released by the team:

“We’re very disappointed to learn of his suspension," the Eagles 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.”

In a statement released by Knott through the team, he expressed his remorse:

“Several weeks ago, I was shocked to learn that I tested positive for a stimulant that is banned by the NFL.  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 sincerely apologize to my teammates, coaches, my family and fans for the impact of my mistake on the team.”

Knott was primarily a special teams player last season and actually played a crucial role in the Eagles Week 1 victory against the Redskins recovering an onside kick.
