T.O. - will/can he play somewhere else this year?

[trying2learn]

Instead of putting this in the other thread, I was hoping one of the posters who is better informed could let me know on the ruling here.

He's suspended for four games and then they are, "Keshawn Johnson-ing" him for the rest of the year. Does that mean they are not accepting/entertaining offers from other teams?

Could they trade/waive him if they wanted?

Is there any chance he plays anymore this year? Obviously not with Philly...but anywhere?
