Among Green Bay's LBs, rookie first-rounder Nick Perry got some time at OLB during Wednesday’s practice in Clay Matthews spot on the left side. Matthews participated earlier in individual drills, but did not take part in the 11-on-11 session. He was replaced on the first team by Erik Walden, last year’s starter on the right side. Jamari Lattimore and Brad Jones, both OLBs in 2011, played ILB on Wednesday.
