Injuries are catching up with the Tennessee Titans.
First-round receiver Corey Davis left practice Thursday to undergo an MRI on his hamstring, per Jim Wyatt of the team's official website.
Coach Mike Mularkey revealed that veteran running back DeMarco Murray is also dealing with a tweaked hamstring that kept him out of Thursday's session.
Wyatt tweeted that Davis "has looked good so far in camp," noting earlier this week that the former Western Michigan star has operated as Tennessee's "X" receiver alongside Rishard Matthews and Eric Decker.
Decker is still learning the offense, but will be asked to immediately step up if Davis is lost for any amount of time. The rookie spent the spring as a limited participant following ankle surgery, so this setback only delays his meshing with quarterback Marcus Mariota.
One of the most exciting rookies on either side of the ball, Davis -- if healthy -- is in position to post impressive numbers in this increasingly tantalizing Titans attack. He'll need to be healthy to do so.
