Source: Kyle Williams top all-star alternate

Despite a marvelous campaign, Buffalo Bills defensive tackle Kyle Williams wasn't chosen to the Pro Bowl roster Tuesday night. Neither were any of his teammates.

WilliamsWilliamsFret not, Bills fans. A charging buffalo helmet almost certainly will be on the field in Honolulu.

Williams just missed the Pro Bowl cut and was named first alternate, an NFL source informed me. Williams will be an immediate roster addition if Vince Wilfork, Haloti Ngata or Richard Seymour get hurt or make it to the Super Bowl, which will be played the week after the Pro Bowl.

There's an excellent chance one of the chosen defensive tackles won't dress for the Pro Bowl. Wilfork plays for the top-seeded New England Patriots. Ngata plays for the Baltimore Ravens, who have clinched a playoff berth.

Seymour won't have a shot at the Super Bowl with the Oakland Raiders, but this was his sixth Pro Bowl selection. Players who have been there before sometimes pull out of the game with an "injury" because they'd rather take a break from football.

Wilfork has been selected to three Pro Bowls, Ngata two.

ProFootballFocus.com, an in-depth analysis site, rated Williams' omission from the Pro Bowl roster its worst snub in either conference.

Teams don't disclose their Pro Bowl alternates because they don't want it used against them in contract negotiations if the player doesn't get added to the roster. More names will leak out in the coming days.
