"It appears Kevin Kolb's first season in Arizona ended three weeks ago, although no one knew it at the time.

Kolb continues to suffer symptoms as a result of the concussion he suffered against the 49ers on Dec. 11.

Kolb hasn't played since, and tests Tuesday revealed he remained "a little slow with some reaction stuff and some processing stuff from my baseline that I'd had earlier in the year," he said.

The problems are "nothing serious," Kolb said, "but it's something I can't play with."

Kolb practiced on a limited basis Wednesday, and it appears he will miss his third consecutive game and seventh of the season Sunday against the Seahawks.

This is the second concussion Kolb has suffered in as many seasons. This one has lingered longer than the one last season.

"Once I got to Friday or Saturday of that next week, I felt pretty good," Kolb said of the one he suffered last year while with the Eagles. "Obviously, this one seems to linger further. Not ideal, but roll with the punches.""
