The Titans won't exercise the fifth-year option on Jake Locker's contract, which means the quarterback will be playing for his future in Tennessee this season.

The decision, which hasn't been announced by the team but was communicated by sources familiar with the situation, comes as no surprise. Locker has a history of injuries and the option is expensive.

The deadline for teams to pick up the fifth-year option for players from the 2011 draft is Saturday.

According to the NFL's collective bargaining agreement, such options pay the top 10 picks the average of the top 10 players at their respective position. For quarterbacks, that figure is roughly $14.6 million.

Another concern for the Titans: in the event of an injury, the option becomes guaranteed.

Locker, who was the eighth overall pick of the 2011 draft, is scheduled to make $2.091 million this season.
