New York Jets tight end Kellen Winslow has been suspended without pay for four games for violating the NFL performance-enhancing drug policy, effective immediately.

He can return Nov. 4 after the Jets' game against the New Orleans Saints.

Winslow has caught 17 passes, a team-high, this season. He's averaging 9.9 yards per reception.

Jeff Cumberland will start in place of Winslow and be backed up by former New England Patriots tight end Zach Sudfeld.

Signed to a one-year, $840,000 contract, the four-game suspension will cost Winslow $197,647 through the loss of four game checks.

"It came as a huge surprise to me when I learned that I tested positive for a banned substance," Winslow said in a statement. "I have investigated all possible sources since learning of the positive test, including possible medical causes, but frustratingly, I do not know the source. I do not take supplements that list any banned ingredients, but the NFL policy is very strict, so I am accountable for the results.

"I sincerely apologize to my teammates, coaches and Jets fans for this situation. I will work extremely hard during this time away from the field and look forward to contributing to the team as soon as the suspension ends."
