A fifth-round draft pick in 2009, Brinkley spent four years in Minnesota before leaving for Arizona last year.
An early down, run-stuffing thumper, Brinkley can fill in at middle linebacker now that the Vikings released Erin Henderson this offseason. However, Brinkley is a liability in coverage and shouldn't be on the field in obvious passing situations.
Brinkley started 15 games for the Vikings in 2012 and complied 99 tackles. He missed all of 2011 with a hip injury.
