Friday at midday is the deadline to vote for last week’s top NFL performances on NFL.com.

If the possibility the Cardinals cut Matt Leinart is very real, what happens next?

If not Brett Favre, then how about Jeff Garcia? Apparently that’s what the Vikings were thinking.

Vikings QB Tarvaris Jackson, in the unenviable position as the backup to Brett Favre, isn’t letting the looming announcement of No. 4′s return change his approach to training camp.

The presumption has been that, at some point, JaMarcus Russell will end up on an NFL roster. No one can really say when, and it’s more likely to be later rather than sooner, but still … eventually.

Brad Childress basically confirmed that Tarvaris Jackson is the top option for the Vikings in the event (however unlikely it appears) that Brett Favre doesn’t return.

Vikings QB Tarvaris Jackson, who sits in the unenviable position of waiting on word from Brett Favre, said it has crossed his mind that he wanted a change, but he never requested a trade.

Vikings vice president of player personnel Rick Spielman said Saturday the team will give Brett Favre time to make a decision on whether to return, and that the team intends to sign free agent RB Chester Taylor.

Introduced by the customary Viking horn, Brett Favre took the field at 6:20 p.m. local time, with fellow Minnesota QBs Tarvaris Jackson and John David Booty. Sage Rosenfels won’t play in tonight’s preseason game against the Chiefs because of an ankle injury.

New Vikings QB Brett Favre will start tonight’s preseason game against the Chiefs and play one to two series, according to a team official.

The Vikings now have four quarterbacks on their roster, and NFL execs I spoke to told me they anticipate Tarvaris Jackson being shopped in the near future now that Brett Favre is in town.

Brett Favre’s presence will help the fantasy value of receivers Bernard Berrian, Sidney Rice, Percy Harvin and tight end Visanthe Shiancoe. Look at Favre as a viable No. 2 fantasy quarterback and worth a middle- to late-round selection.

Brad Childress said he is in no rush to name a regular season starter after the Vikings’ first preseason game, a 13-3 road win over the Indianapolis Colts.

In a perfect world, Minnesota Vikings coach Brad Childress would manage his quarterback competition by giving Tarvaris Jackson and Sage Rosenfels equal reps in Friday’s preseason opener against the Indianapolis Colts.

One day after Tarvaris Jackson revealed that he “felt something pop for a quick second” in his left knee, Vikings coach Brad Childress said he isn’t concerned about the quarterback pushing himself too hard.
