Could Derrick Fisher be leaving the retirement home for a NBA return?

Derrick Fisher could be making his way off the retirement home couch  to play in the NBA again. According to a report by the New York Times, Fisher posted a video on Instagram showing him working out on the court with the caption "Imnotdoneyet"

Fisher won 5 titles with the Los Angeles Lakers during his 18 years there and also spent time on the Oklahoma City Thunder. After retiring he was hired as the coach of the New York Knicks in 2014, but was fired after a season and a half. 

Fisher is 41 years old so it is highly unlikely that he will actually get a chance to play with another NBA team. We could see the Los Angeles Lakers sign Fisher since they like handing out money to players who have done well in the past. Or could we see Fisher making a move to the Warriors? After all the moves they have made this offseason I would not be surprised. 
If Fisher does get signed, it will interesting to see if his contract includes handicapped parking and a space for his walker. At his age, it might take him a little to get to and from practices and games.
