Hall has spent his entire nine-year career with the Cincinnati Bengals and recently visited the Arizona Cardinals. He has returned from two Achilles tendon tears, in 2011 and 2013. Hall, who played in 14 games last season and had two interceptions, has 26 career interceptions.
The Cowboys’ need for cornerback help has not ended with the re-signing of Morris Claiborne last week to a one-year deal worth up to $3.75 million.
The Cowboys had some concerns over the health of Carroll, who suffered a broken ankle last season. Hall’s injury history and age -- he turns 32 in December -- could factor into a contract offer from any team.
Hall played mostly in the slot last season but can also play outside cornerback. His visit could give the Cowboys a chance to replace Carr or give them leverage in attempting to rework Carr's deal for less money.
