Mac's Football blog noted that Nunn has signed on, and that has been confirmed by the Globe.
Nunn was praised by coach Bill Belichick on Friday.
"Terrence [Nunn] has made some impressive plays for us," Belichick said. "He’s a player that was very productive in college in a different type of offense, different type of passing game. He’s adapted to what we’re doing and learning every day and becoming a better route runner and a better technique player to go along with his physical skills. He’s continued to make progress on a steady basis and he’s done a lot of things to catch our eye and the fans’ and everyone else that’s seen him play. He’s still got a lot of things to work on, but he’s making solid progress and had an impressive game last night.
I was pulling for Terrence Nunn to make the 53 man roster, but he was a victim of a stacked WR corp. There was simply no room for him. Well, his impressive performance against the Giants this past Thursday night, 3 for 64 with a 30 yarder, earned him another look on the practice squad.
I'm really happy about this one. I've liked Nunn from the start and thought he was a hard working kid. This will give him a chance to develop and if one of our WR's gets hurt, a shot at making a case for himself.
Good job, Terrence. Good job.
