According to Associated Press sports writer Jon Krawczynski, Tarvaris Jackson said his broken right index finger is feeling better every day. Still, head coach Brad Childress was reluctant on Wednesday to say whether Jackson could play this weekend against Philadelphia.

Jackson broke the finger on his throwing hand in the third quarter of last week's game against Dallas. Both the quarterback and the coach acknowledged that it will be difficult to guide the football with the injury.

"You want a tight spiral and it's hard to spiral the football without your index finger," said Jackson, who wore a splint on his hand and was limited in practice. "That's one of the most important fingers, besides the thumb, to throw the football. I don't want to be out there if I can't control the football."

If Jackson can't go, veteran Kelly Holcomb will get his third start of the season.

Holcomb stayed after practice to take some extra snaps and said he would look forward to playing against one of his former teams.

If Jackson has his way, he'll start against the Eagles. He's coming off a miserable performance against the Cowboys in which he was just 6-of-19 for 72 yards.

"It seems like when I don't play so well, I get hurt and I have to sit out," said Jackson, referring to when he injured his groin in a four-interception day at Detroit in Week 2. "Hopefully I can go out there and play and just get better. ..."

Also on the injury front. ... Running back Chester Taylor (groin), tight end Visanthe Shiancoe (groin) and fullback Naufahu Tahi (knee) were all limited Wednesday.

Stay tuned. ... I'll have more on Jackson, Taylor and Shiancoe after today's practice. ...

Meanwhile, before taking questions during his morning news conference, Childress responded to criticism that the team isn't using rookie running back Adrian Peterson enough.

"We understand here that we have a great talent in Adrian Peterson," Childress said. "We are trying to grow him just like we attempt to grow all of our young guys. I'm sure his role will increase as we go through the rest of this football season, but there'll be times when situations will dictate that we have other folks in the football game."

Peterson got just 12 carries in Sunday's 24-14 loss at Dallas, but Childress said that was "kind of a left-handed game," featuring just 48 offensive plays for the Vikings, including 17 in the first half.

Pass protection is an area that Peterson continues to work on, and so Childress typically likes to go with Taylor in situations where the running back is counted on to pick up a blitz.

Asked if the Vikings would use their running backs any differently this week, Childress said: "I think they'll be similar game plans, similar plays.

"But again, you want to give him the plays that you feel like are good plays for him to look at and we want to use him more and more as we go."

The Vikings are idle this week.
