Rick Campbell is leaving the Edmonton Eskimos to join their provincial rivals in Calgary.
The Stampeders named Campbell their new defensive co-ordinator Wednesday.
Campbell leaves his job as Eskimos special teams coach to join the Stamps.
The move comes after Dave Walkosky resigned as Calgary's defensive co-ordinator earlier this week to become the special teams co-ordinator at Georgia Tech.
A veteran of 13 CFL seasons, Campbell spent 10 years with Edmonton, from 1999 to 2008 and 2011.
He joined Winnipeg in 2009 as the defensive backs coach and special teams co-ordinator before becoming Calgary's running backs coach in 2010.
"Rick is a well-respected coach," Stamps general manager and head coach John Hufnagel said in a statement. "He brings a wealth of knowledge and has a great deal of experience in all three phases of the game."
Edmonton head coach Kavis Reid said it wasn't great timing for the Eskimos to lose Campbell but "we understand that this opportunity helps put Rick a step closer to realizing his ambition to one day become a head coach in the CFL."
