The Green Bay Packers have activated C/G JC Tretter from injured reserve – designated for return, released T Derek Sherrod, signed RB Rajion Neal and LB Joe Thomas to the practice squad and released TE Ike Ariguzo and DE Joe Kruger from the practice squad. The transactions were announced Monday by Executive Vice President, General Manager and Director of Football Operations Ted Thompson.

Tretter, the second of three fourth-round choices by the Packers in the 2013 NFL Draft, missed most of his rookie year after sustaining an ankle injury during organized team activities and has sat out the first nine weeks of this season due to a knee injury he suffered during the preseason.

Sherrod played in 20 regular-season games with one start since being selected by Green Bay in the first round (32nd overall) of the 2011 NFL Draft. He missed all of the 2012 season and the first half of 2013 due to a broken leg he suffered late in his rookie year.

Neal and Thomas both spent the 2014 offseason and training camp with the Packers after originally signing with Green Bay as non-drafted free agents on May 12, 2014. Neal will wear No. 34 for the Packers while Thomas will wear No. 48.
