Mularkey said Davis will not need surgery, and the Titans will evaluate him on a week-to-week basis. Davis suffered the hamstring injury during one-on-one drills in Thursday's practice.
Davis had no obvious cast or wrapping on his hamstring Friday. He signed autographs for fans in attendance for the Titans' special Friday Night Lights practice at Centennial High School in Franklin, Tennessee, although he did not practice.
Davis said his goal is to play in the Titans' season opener Sept. 10, against the Oakland Raiders.
While Davis is out, rookie receiver Taywan Taylor will see a big uptick in repetitions.
