LAKE FOREST, Ill. (AP) The Chicago Bears hired former Purdue defensive coordinator Tim Tibesar as their linebackers coach on Tuesday.
He replaces Bob Babich, who was let go after the season and is now Jacksonville's defensive coordinator.
Tibesar served as Purdue's defensive coordinator and linebackers coach last season after working for three years under new Bears coach Marc Trestman with the CFL's Montreal Alouettes. Tibesar was linebackers coach for two years before becoming defensive coordinator in 2011.
Purdue's defense allowed just under 416 yards per game last season and ranked 11th in the Big Ten. Tibesar was also Kansas State's defensive coordinator in 2007 and 2008 after running the special teams there for a year. He oversaw a defense that registered 30 sacks in 2007.
The Bears also hired Brendan Nugent and Carson Walch as offensive quality control coaches on Tuesday. Both worked for Trestman in Montreal.
Nugent was an assistant on special teams and offensive quality control coach for the Alouettes this past season after spending the previous five at William & Mary coaching both the running backs and tight ends.
Welch spent the past three seasons with Montreal, coaching wide receivers last season after two years as special teams quality control coach.
