MANKATO, Minn. -- Minnesota Vikings wide receiver Cordarrelle Patterson, who left the team's Friday practice after landing awkwardly on his left shoulder following a diving catch, should be back relatively soon.

A league source said Saturday morning that Patterson's injury was "minor in nature," and added it shouldn't take Patterson too long to get back to 100 percent.

The news likely comes as a relief for the 2013 first-round pick, who again led the NFL in kick return average last season but didn't have his fifth-year option picked up this spring. The Vikings have called on Patterson to become a more reliable receiver, after shifting him away from the multi-faceted role he had during his rookie season under former offensive coordinator Bill Musgrave. As Patterson has struggled to master the nuances of route-running, he has seen his role in the offense dissipate. He caught only two passes in 2015 and was targeted with just three throws.

Patterson spent time with a route-running coach this offseason, though, and coach Mike Zimmer sounded encouraged by Patterson's approach during the Vikings' OTAs and minicamp this spring. If the receiver can get back on the field soon, he'll try to make the most of his opportunities to develop in the Vikings' offense.
