Vikings cornerback Josh Robinson has a torn pectoral muscle, an NFL source confirmed Saturday.

The severity of the injury is unknown. Robinson declined to comment on it, but texted he was looking forward to "playing with the Vikings this season."

Robinson was a third-round draft pick in 2012 and has played regularly since. The Vikings took cornerback Trae Waynes with their first round pick this year after drafting cornerback Xavier Rhodes in the first round in 2013.

The Vikings lost two starters, Phil Loadholt and Brandon Fusco, on the offensive line last year because of torn pectoral muscles. Defensive end Brian Robison was limited in the offseason because of a pectoral injury as well.
