Grupe missed his only field-goal attempt in Saturday's 34-6 preseason loss to the Falcons.
Grupe missed a 36-yard attempt after watching Spencer Shrader convert 48-yard and 53-yard field goals earlier in the game. Grupe had previously been viewed as the favorite in the Colts' kicker competition, but his miss Saturday may have opened the door for Shrader to close the gap. Next Saturday's preseason finale against the Lions will be a pivotal game for both kickers.
