JACKSONVILLE, Fla. -- Is Rex Ryan trying to get fired?

Ryan's decision to activate Tim Tebow as the No. 2 quarterback -- and not Greg McElroy -- raises a lot of questions. This move makes no sense on many levels.

First of all, Ryan loses some credibility here because it shows he never seriously considered McElroy as his starting quarterback. How can a player go from a possible No. 1 to No. 3 in one week?

Ryan also is inviting a full-blown, three-way controversy. What if Tebow replaces Mark Sanchez and plays well? Fans will be screaming for Tebow to be the starter, and people will second-guess Ryan for not having gone to Tebow earlier in the season.

There's also the health factor. Tebow, four weeks removed from fracturing two ribs, didn't play in the past two games and has been limited in practice. Now, all of a sudden, he's ready to be the No. 2?

The Jets are indeed a three-quarterback circus. That the game is in Tebow's hometown will add to the story. How long before the home crowd starts chanting for Tebow, a local icon?

The Jets had planned to dress all three quarterbacks, a team spokesman said before the game, but a medical situation involving another player changed the plan. Running back Joe McKnight developed a migraine Sunday morning. As a result, the team felt it needed to activate running back Kahlil Bell.

Still, for the second time in three games, the Jets will have Tebow as the No. 2 quarterback even though he's not 100 percent.

What a mess.

The Jets' other inactives are WR Jordan White, WR Clyde Gates, LB Ricky Sapp, DT Damon Harrison, G Caleb Schlauderaff and TE Dustin Keller.

For the Jaguars, the inactives are RB Rashad Jennings, CB Aaron Ross, RB Maurice Jones-Drew, C Mike Brewster, WR Cecil Shorts, DE George Selvie and DE John Chick.
