Matt Hasselbeck (calf) could be a "stretch" for Week 15, according to beat writer Jim Wyatt. Hasselbeck's injury is not thought to be serious, but there's little reason for him to play at less than 100 percent. Even when the veteran is fully healthy, rookie Jake Locker is more likely to threaten defenses. Locker ran for one touchdown and threw for another in Sunday's narrow loss to the Saints.
