Dallas, TX -- Wade Wilson, the quarterbacks coach of the Dallas Cowboys, was suspended for the first five games of the season and fined $100,000 on Saturday for violating the NFL policy on performance enhancing substances.
In a statement by the NFL, Wilson admitted to purchasing and using a prohibited substance.
The league did not specify what the substance was, but the New York Daily News reported it was human growth hormone (HGH).
Wilson's punishment comes a day after New England Patriots safety Rodney Harrison was suspended four games for admitting to receiving HGH.
According to the Daily News report, Wilson - who retired as a quarterback in 1998 - received HGH when he was a member of the Chicago Bears coaching staff from 2004-06.
"This situation is the result of an uninformed decision that I made, and I accept responsibility for my mistake," Wilson said in a statement released through the NFL. "My actions were the result of trying to improve the quality of my life based upon my 20-plus years of living with diabetes.
"I did, however, make an error. I had a very limited exposure to a substance. It did not have a positive effect on the quality of my life, and I soon discarded it. It was used only by me and not made available to anyone else."
Both Wilson and Harrison were found to be connected to HGH through an Internet drug scam investigation conducted by the Albany (N.Y.) County District Attorney's office, the Daily News reported.
The office told the NFL that both Wilson and Harrison received drugs from Signature Pharmacy in Orlando, which had doctors sign prescriptions for patients they never saw.
According to the report, Albany and Florida law enforcement agents raided the pharmacy in February.
"Upon learning of the very serious nature of this situation, I cooperated fully and honestly with representatives of the NFL and all of the authorities involved," Wilson said.
In Wilson's absence, offensive coordinator Jason Garrett and offensive assistant Wes Phillips will work with the quarterbacks.
"We understand and support the commissioner's decision," Cowboys owner Jerry Jones said in a statement. "Wade Wilson accepts responsibility for his mistake in judgment and recognizes the importance of the NFL's performance enhancing-substance policies. After learning of his error, he cooperated fully with all of the parties involved in this matter.
