IU assistant Johnson headed to Bills

Indiana offensive line coach Bobby Johnson is leaving to take a position with the Buffalo Bills.

Johnson's hiring in Buffalo won't be official until early next week, but he's expected to sign a contract to become an assistant offensive line coach for new Buffalo head man Chan Gailey.

Johnson spent five seasons at Indiana and was one of five former Miami (Ohio) assistants to join Terry Hoeppner when Hoeppner became Hoosiers head coach. Indiana's offensive line improved significantly this fall after an injury-plagued 2008 season, and left tackle Rodger Saffold blossomed into a good NFL prospect.

Head coach Bill Lynch hasn't had to make many hires since taking the top job, as he tried to maintain staff continuity. Indiana returns three starters on the offensive line for the 2010 season.
