Will Kirkpatrick rescue the 49ers’ CB corps after Verrett injury?

COLUMBUS, Ohio — For the second straight week, the 49ers are bringing in a veteran cornerback who is over 30 years old. Once again, it is not Richard Sherman.

Dre Kirkpatrick is signing with the 49ers in the wake of Jason Verrett’s season-ending knee injury in Sunday’s win at Detroit, according to multiple reports.

Kirkpatrick, who turns 32 on Oct. 26, will enter the mix at a position where the 49ers added to their depth last Monday with Josh Norman, 33.

Kirkpatrick played last season for the Arizona Cardinals after eight years on the Cincinnati Bengals, who drafted him in the 2012 first round. He has 13 career interceptions and 72 pass defenses in 78 starts and 113 games.

The 49ers lost Verrett during a fourth-quarter freefall in their season-opening, 41-33 win over the Lions. Rookie Deommodore Lenoir started at the other cornerback spot (and played a NFL-high 90 snaps).

Potential starter Emmanuel Moseley did not play Sunday nor has he practiced since injuring his knee Sept. 3, but coach Kyle Shanahan is hoping — not guaranteeing — he’ll be available for this Sunday’s game at Philadelphia.

Other cornerbacks on the roster are Ambry Thomas, a third-round pick, and veteran Dontae Johnson.

Verrett will head onto injured reserve along with running back Raheem Mostert, who is out at least two months to repair knee cartilage.
