The Dallas Cowboys have added some new faces to their training camp roster.

With news quarterback Zac Dysert is to undergo surgery on a herniated disc suffered during the first official week of camp, the team has made the decision to add some competition to the depth chart behind starter Dak Prescott. According to Todd Archer of ESPN, they've signed a McCown to the roster -- obviously not Josh, though.

It's younger brother Luke, and it's a one-year deal for 2017.

The junior McCown enters as a career QB2 who was a former fourth-round pick of the Cleveland Browns in 2004. The journeyman QB has also spent time with five other NFL teams before now joining the Cowboys. He'll battle Kellen Moore and Cooper Rush for a spot on the active roster.

Not content to sit tight with just that signing, the team has also signed wide receiver Javontee Herndon -- whom they worked out earlier in the week. The 26-year-old was undrafted out of the University of Arkansas, signed in 2014 by the now Los Angeles Chargers.

He'll join a stacked WR corps for the Cowboys, likely more of a camp body at this point unless he proves otherwise.
