Bishop has reached an agreement to sign a one-year contract with the 49ers, Matt Barrows of the Sacramento Bee reports. With Patrick Willis and Chris Borland both retiring, the 49ers are exploring all avenues to address the inside linebacker position. The team still has All-Pro Navorro Bowman (knee) under contract, but Bowman missed all of 2014 in the aftermath of a torn ACL. Bishop, a regular starter for the Packers in 2010 and 2011, has just seven tackles over the last three years. If Bowman is healthy, it's hard to envision a scenario in which Bishop has any kind of IDP relevance. Meanwhile, Michael Wilhoite is still the favorite to start next to Bowman.

Bishop re-signed with the Cardinals on Wednesday, Yahoo! Sports reports. Bishop was signed and released by the Cardinals last month, but will now be brought back to provide depth at linebacker for Arizona.

The Cardinals have released Bishop, the team's official site reports. The report suggests that even with Alex Okafor not expected to play Monday night, the Cardinals still roster nine linebackers at this time, thus making Bishop expendable.

Bishop (knee) will sign with the Cardinals, NFL.com's Ian Rapoport reports. The 30-year-old has endured two straight injury-filled campaigns, but assuming he can re-prove his health, he'll bolster the Cards' depth at inside linebacker in the wake of the team's recent release of Ernie Sims.

ESPN Vikings reporter Ben Goessling expects free agent LB Desmond Bishop to move on. Goessling points out that Bishop has had more season-ending surgeries (two) than starts (one) over the last two seasons. The latter surgery was to repair a torn ACL, something 30-year-old players often struggle to return from. Bishop is going to have to accept a non-guaranteed one-year deal and prove himself in camp somewhere.

Vikings LB Desmond Bishop has been diagnosed with a torn ACL, and is done for the season. The reserve outside linebacker went down in Sunday's loss. Bishop ends 2013 having played just 29 snaps. Signed to a one-year, $850,000 deal in June, he'll be a free agent at season's end. Going on 30, Bishop should be close to 100 percent for next summer's camp, but is obviously going to have a hard time getting deal.

Vikings LB Desmond Bishop is done for the day in Week 6 with a knee injury. It looked serious. Bishop's snaps have been limited this year after the Vikings signed the ex-Packer in late June. We suspect he'll miss extended time.

Vikings LB Desmond Bishop didn't play a snap in Week 1 against the Lions. The Vikings' starters are Erin Henderson (MLB), Chad Greenway (SLB), and Marvin Mitchell (WLB). Bishop has not earned defensive playing time and is a strict backup. The Vikings signed him to a one-year, $850,000 deal in June.

Desmond Bishop still hasn't won the Vikings' starting weak-side linebacker job. "As we speak, Marvin Mitchell is still our starting" weak-side 'backer," coach Leslie Frazier said Monday. Bishop played well in August, but may still be learning Frazier's defense. To open the season, the Vikings will likely use MLB Erin Henderson and SLB Chad Greenway as their two linebackers in the nickel.

Coach Leslie Frazier confirmed Desmond Bishop's roster spot is in jeopardy. Bishop had to leave last week's preseason opener early due to groin pull. That came on the heels of questions about his health after tearing a hamstring in 2012. "So much of this is about how he plays over the next two weeks," Frazier said. "Or if he's not available because of his injury. I can't say it any simpler than that." When active, Bishop has been backing up Marvin Mitchell at weak-side linebacker.
