Browns tight end Kellen Winslow is listed as questionable for Monday night’s game against the Giants, but Adam Schefter of NFL Network reports that in reality, he’s definitely not going to play.

Steve Heiden will start at tight end in Winslow’s place tomorrow.

Winslow has been out the last four days, and no one in Cleveland is saying what’s wrong with him. Schefter reports that even people inside the building don’t know; the nature of Winslow’s illness has been kept from multiple team employees.

We’ve heard that Winslow is on antibiotics for an infection, and that he’s had bad swelling south of the border.
