Jackson: "It doesn't look good for me."

Vikings QB Tarvaris Jackson left open the possibility of playing Sunday against the Philadelphia Eagles.

"It doesn’t look good for me," he said, "but you never know."

With a broken finger and an ailing groin, Jackson is expected to sit out Sunday, giving way to veteran Kelly Holcomb.

Jackson is listed as questionable, and Vikings coach Brad Childress said he is still "debating the old game-time decision." Childress added that Jackson would either start or be the third quarterback, which means Brooks Bollinger would likely be Holcomb's backup Sunday.

Holcomb, meanwhile, is feeling much more comfortable in the offense now, he said.

"You know who you’re playing with," he said. "It was a lot better for me, I felt. I felt like I threw the ball better."

Since he was traded from the Eagles, Holcomb said his familiarity with the team's defense should help him.

"Hopefully, that will benefit me, knowing a lot of what they do," he said. "They’ve got some unorthodox stuff that they do on defense. They try to fire you up on third down. We’ve got to be able to answer what they throw at us. If we don’t, it could be a long day."

In other injury updates, RB Chester Taylor is listed as probable, and he will play Sunday, although rookie Adrian Peterson may handle the bulk of the workload.

S Dwight Smith was ruled out, which means Tank Williams will start again, while LB Vinny Ciurciu is listed as doubtful.

TE Visanthe Shiancoe and G Anthony Herrera are also probable.
