Why did the Tennessee Titans start Mason Rudolph at QB over Will Levis vs. the Buffalo Bills? Here's Brian Callahan's explanation of the timeline.

Titans starting quarterback Will Levis is out due to an injury to his throwing shoulder, leading to backup Mason Rudolph getting the start against the Buffalo Bills on Sunday.

According to Tom Pelissero of the NFL Network, the Titans will start veteran Mason Rudolph at quarterback on Sunday against the Buffalo Bills as Levis continues to deal with a shoulder injury. Levis was ruled out for Sunday’s game, and the Titans signed quarterback Trevor Siemian from the practice squad to back up Rudolph.
