Kyle Boller could get the call

The Oakland Raiders’ muddled quarterback situation didn’t clear up much Thursday.

In fact, if anything, it looks like the chances have increased that No. 3 quarterback Kyle Boller will make his Oakland debut at Denver on Sunday. Still, I expect this saga to drag out perhaps until game day.

According to the Oakland Tribune, Raiders coach Tom Cable said No. 2 quarterback Jason Campbell’s mobility is “iffy.” Cable said Wednesday that Campbell, who hurt his knee in a poor effort in a loss at San Francisco on Sunday, would start against the Broncos if he was able to play and if starter Bruce Gradkowski couldn’t play. Gradkowski has missed the past seven quarters with a shoulder injury.

Both Campbell and Gradkowski were limited in practice Thursday, although Gradkowski hasn’t done much at all. Unless Gradkowski improves at an unexpected rate, it looks like Campbell or Boller will play at Denver. It’s clear Campbell’s knee will need to improve to play.

Thus, it’s a real possibility that Boller will start for the first time in two years. According to ESPN Stats & Information, Boller has the longest current losing streak of any quarterback in the NFL. He has lost his past 10 starts. Boller, who has started 46 NFL games, played for Oakland offensive coordinator Hue Jackson in Baltimore, so there is familiarity in the team’ system if he needs to play.

Meanwhile, Oakland tailback Darren McFadden was limited for the second straight day with a hamstring injury that has kept him out of the past two games. For Denver, left cornerback Champ Bailey was limited with a rib injury that kept him out of Wednesday’s practice. Receiver Eddie Royal was out for the second straight day with a groin injury.
