Former Bears and Falcons OT Kevin Shaffer has retired from football. The 32-year-old has "no plans to return." Now pursuing a coaching career, Shaffer is currently working with draft-eligibles at the Senior Bowl and in pre-Combine training. Shaffer was considered one of the NFL's top zone-blocking left tackles during the early- to mid-2000s with Michael Vick and Warrick Dunn. He later busted in power-blocking schemes with Cleveland and Chicago.
