Alford, 25, started 31 of 33 career games at Boston College and was a key performer in a BC offensive line that helped Michael Cloud become the school's all-time leading rusher with a career total of 3,597 yards, recording 147 knockdown blocks during his three-year collegiate career and earning first-team All-Big East Conference honors as a senior.
Franz, a free agent from the University of Tulsa, was released by the Packers in the team's final cutdown on Sunday. The 6-foot, 194-pound defender had 4 solo tackles and one interception during the preseason, making a 42-yard return of the latter in the August 26 Bishop's Charities Game against Cleveland. He also had been credited with 2 passes defensed and 2 special teams stops.
To make room for Franz, the Packers released rookie cornerback Erwin Swiney, who was signed to the practice squad on Monday. Swiney closed out the preseason as the Packers' second-leading tackler with 19 stops, 18 of them solo. He also recorded one quarterback sack.
