Colvin was second to Tampa Bay's Derrick Brooks in fan voting, which counts for one-third of the selection process. But Brooks, Washington's LaVar Arrington and San Francisco's Julian Peterson were the outside linebackers chosen as the other voters went for tackle totals over sacks.
Brooks is fifth in the NFL in tackles with 99, Peterson has 88 and Arrington has 86 in addition to 10 sacks. Brooks and Peterson play on playoff qualifiers.
Colvin, who has 56 tackles this season, has also had trouble in pass coverage.
"I probably have to cover a little better cause my rushes come when I'm a nickel end, so they probably figure I wasn't a good enough outside linebacker."
The questions quickly turned from Pro Bowl discussion to contract talks.
The usual quite Urlacher continued to praise his teammate.
"As a player I definitely want him back because he takes a lot of heat off me with the pressure he gets on the quarterback," Urlacher said. "And he's always talking out there, keeping guys in the game. I really hate to see him go if he has to leave, but that's the way it goes sometimes with the salary cap and the players we have here already that make so much money. It'll be interesting to see, but there's always the franchise tag they could stick on him for one more year. We'll see what happens. I'd love to have him back, but I just don't see it happening."
