FRISCO, Texas -- The Dallas Cowboys have placed Pro Bowl center Travis Frederick and veteran wide receiver Terrance Williams on injured reserve and activated defensive tackle David Irving from the suspended list, according to multiple sources.
With the moves, the Cowboys have 52 players on the roster.
Frederick has been battling the effects of Guillain-Barre syndrome, an autoimmune disease that affects the nervous system, since training camp. The Cowboys opted to keep him on the 53-man roster at the start of the season, keeping open the possibility of him playing sooner than many expected.
