Winslow, who was averaging 42.5 yards per game for the 1-3 Browns, missed his fourth day of practice on Saturday for what is being reported as an undisclosed illness.
The "illness" has become so bad the former Miami star has been hospitalized and is being treated with antibiotics. News has already been leaked that the problem is an inflammation in his testicles -- so bad that Pro Football Talk said they "swelled to the size of grapefruits."
No other news outlet, however, has been as ballsy as PFT, saying that the injury is likely unrelated to any previous problems he's had with his knee.
Winslow has undergone four knee surgeries and has had to play through pain throughout most of his four-year NFL career.
His illness is not believed to be related to any of his previous injuries.
The Browns will start Steve Heiden in his place.
