As posted in the Insider section at ESPN:

Toronto Raptors
Most likely amnesty cut: Amir Johnson
How likely to use amnesty this season: Jump ball
Other amnesty candidates: Jose Calderon
Notes: The Raptors now say they intend to keep Calderon to play him with Kyle Lowry. Using the amnesty clause on Amir Johnson remains a possibility, especially since he would likely be picked up on waivers, which would save the team additional money.
