Hauschka converted 24 of 27 field goals and 46 of 48 extra points this season and set the postseason franchise-mark with three field goals made in the NFC Wild Card game at Washington while kicking with an injured calf. Longwell last kicked with the Vikings in 2011. He did not play in the NFL this season.
