Round and round and round he goes. Where he stops, nobody knows.
In return, the Thunder got a $2.85 million trade exception and the rights to Tomislav Zubcic.
Ridnour, 34, has a fully nonguaranteed contract for next season that can be waived until July 10, which makes him a very tradeable asset.
A 12-year veteran, Ridnour appeared in 47 games last season averaging 4.0 points and 2.0 assists for the Magic.
The Thunder will have one year to exercise the trade exception. Zubcic was the 56th overall pick in the 2012 draft and has yet to play in the NBA.
