Welcome injury news for Cards, 49ers

A look at the implications for two positive developments on the injury front Tuesday:

  • Arizona Cardinals: Kevin Kolb has a "thigh contusion" and should practice as early as Wednesday. Injuries ruined Kolb's first season with the Cardinals. He needs to remain on the field to hold off John Skelton for the starting job this season. Further, the Cardinals need both quarterbacks healthy to maximize their chances for getting the best quarterback on the field. So much is at stake for Kolb and the organization, including coach Ken Whisenhunt. Initial indications suggested Kolb would be OK after absorbing a knee to his thigh in practice Monday. Now we know.

  • San Francisco 49ers: Rookie offensive lineman Joe Looney suffered a serious foot injury during Senior Bowl week. The injury hurt Looney's draft stock, allowing the 49ers to snag him relatively late in the draft (fourth round). The fact that Looney has passed a physical and can make his NFL training camp debut gives the 49ers another option at a position (right guard) carrying some uncertainty, and depth at the other guard spot as well. Alex Boone has been the favorite to win the job on the right side even though he's probably best suited at tackle. Free-agent addition Leonard Davis provides an experienced alternative. Looney might represent the longer-term future of the position in San Francisco if he develops as planned.

All for now. Back in a bit with some telling numbers on Braylon Edwards, the Seahawks' newest addition.
