The Chargers issued a release earlier this week announcing the arrival of former Dolphins G.M. Randy Mueller, and other internal moves.  One of them was the retirement of assistant G.M. and director of player personnel Buddy Nix, who is 68.

But now there’s talk that this was something other than a retirement.  A league source opined that the situation doesn’t “feel right” to him.  “I thought Nix and [G.M.] A.J. [Smith] were tight,” the source said.

The San Diego Union-Tribune reports that the league recently was abuzz with speculation that Nix was forced out, and that he’ll find new work soon.  He reportedly flew to Tennessee on Sunday night with agent Jimmy Sexton, who represents many key figures in football, including Dolphins V.P. of football operations Bill Parcells.

But Nix said on Wednesday that he has no immediate plans to come back.  “I’ve got no idea what I’m going to do,” Nix told the Union-Tribune.  “It’s only been one day.  I still haven’t gotten over the time change.  I’m trying to adjust to the fact if I want to play golf, I can.  I can do what I want to.  That’s going to be a little bit of a change.”

It’s still unclear whether Nix resigned or retired.  “The Chargers, in the release about the retirement, that was exactly what we said.  But you think about how permanent that sounds.  You never know how it’s going to go months from now.  I’m certainly happy with the decision.  I do not have any plans other than to golf.”
