Gary Guyton became the newest Cowboy on Wednesday, practicing for the first time. He agreed to terms Tuesday after working out for the Cowboys, the second inside linebacker signed since Oct. 24.
"We’re a little thin there with the injuries, so we just got to make sure we have another guy who can go in and play defense for us," Cowboys coach Jason Garrett said. "We’re hopeful at some point that he can help us on special teams as well."
The Cowboys have had a string of injuries at the position.
Sean Lee is out for the season with a foot injury. Orie Lemon (hamstring) was placed on injured reserve Wednesday to make room for Guyton. Dan Connor was limited in practice with a neck injury that kept him out of Sunday's game as well as all but 10 plays of the Giants game.
Ernie Sims, signed Oct. 24, was forced to start against the Falcons and played 45 of 67 plays.
Guyton made 32 starts with 4.5 sacks and three interceptions from 2008-11 with the Patriots. He was in the Dolphins' training camp this summer.
"I'm comfortable in this defense," Guyton said. "I’ve done it when I was in New England. I’m comfortable inside, outside. I did both things out in New England, so I’m comfortable with the 3-4 defense."
