Cobb visited with the Cowboys at The Star on Monday, taking a physical and meeting with coaches and staff.
While dealing with hamstring woes and a concussion previous year, Cobb played in just nine games, recording 38 receptions for 383 yards and two touchdowns. Cobb joins Allen Hurns and Tavon Austin as a slot player.
If healthy, the Cowboys are likely hoping he could bring the type of numbers he had in 2014 when he brought in 91 catches for almost 1,300 yards and 12 touchdowns.
Cobb appeared to acknowledge the move on Twitter.
According to Packers.com, Cobb has played with the Green Bay Packers since 2011. He's worn out the Cowboys previously, including compiling eight catches for 116 yards and seven catches for 62 yards in Packers' postseason wins over Dallas in 2014 and 2016. The Cowboys were forced to attempt the receiver by committee approach as the roster did not have a true number one receiver.
With the Cowboys, Cobb will likely try to re-establish his value while filling in a gap created by the departure of slot receiver Cole Beasley, who signed a four-year, $29 million deal with the Buffalo Bills in free agency. Cobb is a logical fit and he's more than capable of filling the void, as he's run 81 percent of his routes from the slot over the last three seasons in Green Bay. "He's a great friend of mine".
The Cowboys didn't know if Terrance Williams would play at all in the 2018 season due to him being both injured and suspended.
"We want to thank Clay for all that he has contributed to the Packers over the past 10 seasons".
