Radunz sustained a knee injury during Saturday's training camp practice, Katherine Terrell of ESPN.com reports.
Radunz tweaked his knee early in Saturday's practice, and he'll undergo further tests to determine the severity of the injury and whether he'll be available for the Saints' preseason opener against the Jaguars on Saturday, Aug. 15. William Sherman would be in line for more snaps at offensive guard if Radunz were to miss time.
