Grupe reverted to the Colts' practice squad Monday, per the NFL's transaction log.
Grupe was elevated to the Colts' active roster for Sunday's game against the Jaguars, during which he connected on both of his field-goal attempts and his lone point-after try. He served as the Colts' starting placekicker ahead of Michael Badgley, and Grupe should have another opportunity to kick this Sunday against the Seahawks.
