found this on the NFL feeds on the LB front page:

"FLAGSTAFF, Ariz. (AP) -- Arizona wide receiver Anquan Boldin, the 2003 NFL offensive rookie of the year and the Cardinals only Pro Bowl player, injured his right knee Tuesday morning while loosening up for practice and was carted from the field.

Boldin experienced soreness in the same knee Monday and sat out a morning practice but participated in an afternoon walkthrough.

His tests results weren't immediately available."

Now who has the best young WR tandem in the NFL? Just kiddin, I was hoping to see how well the Card and Lions WR duos compared this season. Puts a lot of pressure on Fitzgerald now - let's hope the knee injury isn't serious

It gets worse....

FLAGSTAFF, Ariz. (AP) -- Arizona wide receiver Anquan Boldin, last season's offensive rookie of the year, underwent arthroscopic knee surgery Wednesday and could be sidelined at least eight weeks.

Coach Dennis Green initially said an MRI found ``a slight tear'' in the cartilage and thought Boldin would be able to return within two weeks. But during the procedure, doctors found and repaired a more significant tear, Green said.

``We are looking at what is typically an eight- to 12-week injury,'' Green said about the length of Boldin's rehabilitation.
