Head coach Jeff Fisher spoke highly of the man who worked for him from 2004 until 2010, when Fisher left the Titans.
"I feel very fortunate that we were able to bring Dave aboard," Fisher said. "He's been in a variety of roles in this league, from position coach all the way up to head coach. His vast knowledge and experience will be valuable assets to our staff, and I'm really excited to have the opportunity to work with Dave again."
McGinnis had a similar title in Tennessee, as a senior assistant coach. He also coached the linebackers there.
