(AP) - The Cleveland Browns are sending tight end Kellen Winslow to the doctor for tests after he missed his second straight day of practice with an unspecified ``illness.''

Browns coach Romeo Crennel says Winslow has been sick for two days. Crennel would not say if he would play in Monday night's game against the New York Giants.

``He's a valuable piece to the puzzle,'' Crennel said Thursday. ``I know he'll want to play, and he'll do everything he can to play.''

Winslow caught 82 passes and made the Pro Bowl last season. So far this year, he has 19 catches and one touchdown for the Browns (1-3).

The 25-year-old has undergone four knee surgeries since entering the league. He also missed the entire 2005 season after a near-fatal motorcycle accident.
