Vikings' Blake Cashman: Underwent finger surgery

Cashman suffered a finger injury that required surgery Wednesday, Kevin Seifert of ESPN.com reports.

Coach Kevin O'Connell said Cashman will return once his stitches heal. It's not a long-term issue, and Cashman should be fine for Week 1. Signed to a three-year deal back in March, Cashman is coming off a career year last season in Houston, finishing with 106 tackles (56 solo), two sacks, one interception and one fumble recovery. He should be a tackling machine for Minnesota.
