Amidst rumors of a possible looming suspension for starter Ezekiel Elliott, the Dallas Cowboys workout two free agent running backs on Thursday.

Heading into training camp next week, the Dallas Cowboys appear to be pretty set at the running back position. Along with the NFL’s leading rusher from last season in Ezekiel Elliott, the Cowboys also have veterans Darren McFadden and Alfred Morris on the depth chart. Throw in undrafted rookie Jahad Thomas out of Temple, and the team seemingly has four backs they can carry into camp.

But amidst rumors of a possible suspension looming over Elliott due to an alleged domestic violence incident from last year, the Cowboys appear to be considering adding a bit of insurance to the position.

It was reported on Friday that the Cowboys brought in two veteran running backs who are currently free agents for a workout on Thursday. Those players being former Jacksonville Jaguar Denard Robinson and Ronnie Hillman, most notably from the Denver Broncos.

Robinson is most famously a former college quarterback who made the switch to running back. The 26-year old offensive weapon, who can make an impact on special teams as a returner and as a wide out, has played the last four years with the Jags. Unfortunately, after posting 582 rushing yards and four touchdowns for Jacksonville in 2014, Robinson saw his starts and production dwindle down dramatically ever since.

The 25-year old Hillman exploded for 863 rushing yards and seven scores during the Broncos’ Super Bowl run in 2015. But the former 2012 third round selection has struggled ever since, playing for both the Minnesota Vikings and the San Diego Chargers last season.

What these workouts could confirm is the fact the Dallas Cowboys have some level of concern about Ezekiel Elliott’s availability and want to make sure they have adequate depth behind him in order to insure his possible absence doesn’t hinder the team. Or the Cowboys’ front office could simply be doing their due diligence and looking for some fresh legs to add for their upcoming camp.
