Just a few days ago, Derek Fisher posted a video of himself on Instagram working on his jumpshot and some dribble moves. At the time, he gave no indication that he was looking to get back into the game as a player. Just a couple days later, that appears to be exactly what he's doing.

Last night, Fisher posted another workout video on his Instagram, only this time, there was a hint. At the end of the caption, Fisher included the hashtag “#Imnotdoneyet.”

Take a look:

Speculation began to build, and now ESPN's Ian Begley has this to report:

Sources told ESPN on Wednesday that Fisher has indeed been “exploring options and expressing interest in playing again.”

Presently, there's no indication of a specific team expressing interest in Fisher. There's also no indication if Fisher is looking to play in the NBA again or potentially abroad.

This is a very rare phenomenon in the NBA, and in sports overall. As far as I can find, the only head coach to come back and play in the NBA was Magic Johnson (there have been various player-coaches). Magic came on as the interim coach for the Lakers in 1993-94, but he re-signed after going 5-11. That would make Fisher the first person in NBA history to coach a team for a full season (the 2014-15 Knicks) before making a comeback as a player later on.

The 42-year old was fired by former head coach and current New York Knicks president Phil Jackson earlier this season. Since, he has made numerous television appearances as an analyst for NBA TV and TNT.

Fisher played 18 seasons in the NBA, winning five titles alongside Kobe Bryant with the Los Angeles Lakers. He holds NBA records for most playoff games participated in with 259 and most playoff games won, with 161.
