It's tough to tell what Marcus McNeill is enjoying more: retirement or the hints he could come out of it.

The ex-Chargers left tackle created his own social-media stir this week, suggesting he will attempt a career comeback. The two-time Pro Bowler retired after the 2011 season amid recurring spinal issues.

Alvin Keels, his agent, settled the confusion via text Friday morning.

He was asked if McNeill is planning a return to the game.

"No, he's not," Keels said.

McNeill, 29, began his fun Thursday afternoon on Twitter. At 2:42: "Wow." At 3:55: The #Chargers are moving along without me.. what gives??" Again, at 3:55: "Dont call it a comeback #staytune."

That last one uprooted his Twitter following of 18,000-plus people. The Chargers' post-McNeill era has gone less than swimmingly so far, as they turned to Jared Gaither at the position. He pocketed $9 million for four games in 2012 before his Wednesday release.
