A day after Corey Davisunderwent an MRI on his hamstring, Titans coach Mike Mularkey said on WGFX-FM the first-round pick will be out at least a week, and will be week-to-week from there.
Hamstrings are delicate injuries for receivers, because they're easily aggravated and don't heal quickly. Simply, the quickest way to get back on the field is to shut the player down and do nothing but rest and treatment.
Davis has been playing the role of X receiver alongside Rishard Matthews and Eric Decker, with the latter likely taking Davis' reps while the rookie is away. Davis will also suffer the results of missing time and practice with quarterback Marcus Mariota, delaying their acclimation.
One look at Davis' college film tells you everything you need to know about why Tennessee selected him fifth overall. When we'll see that on an NFL field remains to be determined.
