The Green Bay Packers will reportedly add a safety ahead of Friday's start to training camp.

According to Bill Huber of Packer Report, Green Bay is set to sign undrafted free agent Ryan McMahon, who took part in the Packers rookie tryouts back in May. He went undrafted out of Sacramento State this past April.

McMahon (5-11, 207 lbs.) spent his first three seasons at USC, where he led the Trojans in special teams tackles as a sophomore (nine). He transferred to Sacramento State in 2011, and later became an All-Big Sky selection after tallying 97 tackles, 1.5 sacks, two forced fumbles and an interception as a senior. He finished his collegiate career with 183 tackles.

At his pro day in March, McMahon ran the 40-yard dash in 4.44 seconds, posted a 38-inch vertical and did 14 reps at 225 pounds.

Adding McMahon would bring the Packers to 88 players out of possibly 90 to start camp.
