The Titans fired head coach Brian Callahan on Monday in the midst of his second season with the team, logging a 4-19 record over his time in Tennessee. Senior offensive assistant Mike McCoy was named Callahan's replacement as the interim head coach. He'll be tabbed with trying to turn around the last-place Titans, who'll take on a Patriots team that's 4-2 and unexpectedly in first place in the AFC East entering Week 7.
