The Green Bay Packers have signed QB Joe Callahan to the active roster from the practice squad and placed CB Quinten Rollins on injured reserve. The transactions were announced Monday by Executive Vice President, General Manager and Director of Football Operations Ted Thompson.

Callahan, a 6-foot-1, 216-pound second-year player, was originally signed by Green Bay as an undrafted rookie out of Wesley College on May 6, 2016. After being released by the Packers on Oct. 13, 2016, he spent time with the New Orleans Saints and Cleveland Browns on the active roster before being signed to Green Bay's practice squad on Dec. 2, 2016. He was signed to the active roster by the Packers on Dec. 17, 2016, where he spent the rest of the season. After being released following training camp, he has spent the first six weeks of this season on the Packers' practice squad. In 2015, he became the first NCAA Division III quarterback to throw for 5,000 yards in a season, earning the Gagliardi Trophy, the highest award in Division III football.
