The timing could not be worse for the Titans. Locker missed five games last season with an injured left shoulder for a team that lost four of its first five games. The Titans now are off to a strong start, and Locker certainly is a reason why.
Locker currently is the third-ranked quarterback in the AFC by passer rating behind Denver's Peyton Manning and Philip Rivers of San Diego. Locker currently has a 99 passer rating and is completing a career-high 62.2 percent of his passes with six touchdowns and no interceptions.
The Titans wrap up a three-game home stand against the Chiefs on Sunday before visiting Seattle (4-0) on Oct. 13. They host San Francisco (2-2) before their bye. If Locker is out for only a month, he could be on target to return Nov. 3 when Tennessee visits St. Louis.
