No timetable for Winslow's release from hospital
Winslow was injured in an accident that sent him flying over the handlebars of his newly purchased motorcycle Sunday night.
The Browns issued a statement saying his knee will continue to be re-evaluated but declined to provide any specifics.
The 21-year-old tight end remains hospitalized at the Cleveland Clinic and a timetable for his release has not been determined.
The team also reported that Winslow is in good spirits. He has had a number of visitors over the last few days, including team president John Collins, general manager Phil Savage, coach Romeo Crennel and teammates.
Winslow's injuries are another setback for him and the struggling Browns. His rookie season ended when he broke his right leg during an onside kick in a Week 2 loss against Dallas. He lost a $5.3 million bonus last season because of the leg injury that dealt a severe blow to Cleveland's offense.
With his leg still on the mend, Winslow purchased a sport bike last month and was learning how to ride it in a parking lot when he hit a curb. He complained of chest pains after the crash.
Winslow's use of a motorcycle may have violated standard NFL player contract language that prohibits players from engaging in dangerous activities. If so, Cleveland could require him to pay back a $4.4 million signing bonus he received in March.
The Browns have declined to comment on his contract.
Winslow held out last year before signing a $40 million contract -- a record for a tight end -- as the No. 6 pick in the NFL draft.
