The Dallas Cowboys signed tight end Dallas Walker, an undrafted rookie out of Western Michigan in 2012 who spent time with the San Diego Chargers in 2013.

He will enter training camp battling for a roster spot fifth on the tight end depth chart behind Jason Witten, Gavin Escobar, James Hanna and Jordan Najvar. At 6-feet-6 and around 235 pounds, Walker has an opportunity to make a mark for himself as a blocking specialist.
