Minnesota Vikings defensive lineman Spencer Nealy has been suspended without pay for the first four games of the season for violating the NFL policy on performance enhancing substances.

He's eligible to return following the Vikings' Sept. 28 game against the Atlanta Falcons.

Nealy issued a statement saying he tested positive for a stimulant.

"?Recently I learned from the NFL that I tested positive for a stimulant that is banned under the NFL policy," Nealy said. "I worked with my agent and the union to investigate the test results, and I learned that a supplement I took contained a banned stimulant. I understand that the NFL policy is very strict, and I take responsibility.

"I?'m very sorry for the impact of this situation on my teammates, the Vikings organization and Vikings fans. I will work extremely hard during training camp, and during the suspension, I will stay in top shape and will be ready to contribute upon my return.?"
