Tarvaris Jackson injury might cause Seahawks to re-evaluate QB situation

SEATTLE -- At least in the short term, the Seattle Seahawks might need a new backup plan at quarterback in light of the ankle injury that Tarvaris Jackson sustained in Friday night's preseason opener.

Seahawks coach Pete Carroll said following the Seahawks' 22-20 loss to the Denver Broncos that Jackson's injury is a sprain and not a break. He estimated that it could keep Jackson out for two weeks. That timetable would put him on track to return before the regular season, but it could necessitate the addition of another quarterback in the meantime. Carroll wasn't sure.

"I don't know. We'll see. I don't know about that yet," Carroll said. "We'll have to see how it looks tomorrow. The ankle did not swell up much, so we'll see what that means."

R.J. Archer is Seattle's third quarterback behind Jackson and Russell Wilson. The Seahawks could go with only two quarterbacks until Jackson returns, but that wouldn't be an optimal situation. Archer has never thrown a regular-season pass in his NFL career and has not been particularly impressive during training camp, nor was he during offseason workouts. That could make it a challenge to evaluate the wide receivers who are competing for roster spots and playing time on the back end of the depth chart.

One option for the Seahawks is B.J. Daniels, who was a quarterback with Seattle before converting to wide receiver this offseason.
