Knizner has no structural damage in his groin, Jim Hayes of Bally Sports Midwest reports.
EDGE Analysis
Knizner was placed on the 10-day injured list Wednesday after taking a foul ball to the groin in the fourth inning of Tuesday's blowout loss to the Marlins, but it sounds like he'll be able to return to the Cardinals' active roster shortly after the All-Star break. Ivan Herrera will serve as the backup to Willson Contreras in the meantime.
