The Green Bay Packers have released C/G Duke Preston and placed TE Devin Frischknecht on injured reserve.
Preston signed with the team as an undrafted free agent in March after four seasons with the Buffalo Bills.
Frischknecht, a non-drafted rookie from Washington State, signed with the Packers in June and suffered a broken leg in the Packers 31-21 win over Buffalo last Saturday night.
