The Dallas Cowboys continued hosting national draft prospects Wednesday, with Oklahoma State running back Joseph Randle among those visiting Valley Ranch.He is one of at least four running backs the Cowboys will host. Arkansas’ Knile Davis and Michgian State’s Le’Veon Bell are expected as national prospects, and TCU’s Matthew Tucker will attend Dallas Day next week when area prospects will work out for the Cowboys.Dallas is in the market for a No. 2 running back. Felix Jones, a free agent, remains unsigned. He rushed for 2,728 yards and scored 15 touchdowns in five seasons after the Cowboys made him a first-round pick. Phillip Tanner and Lance Dunbar were No. 3 running backs in 2012, and both return, but Cowboys executive vice president Stephen Jones has said the Cowboys will seek a primary backup to DeMarco Murray.The Cowboys have a maximum of 30 national prospects they can host. TCU receiver Josh Boyce and Clemson receiver DeAndre Hopkins were among the visitors Tuesday. First-round prospects including Alabama guard Chance Warmack, North Carolina guard Jonathan Cooper, Missouri defensive tackle Sheldon Richardson and Texas safety Kenny Vaccaro are among others with scheduled visits.Cowboys re-sign ArmstrongThe Cowboys have brought back receiver Anthony Armstrong a week after releasing him. Dallas waived him March 27, the same day they renegotiated the contract of backup quarterback Kyle Orton, to make room for the signings of safety Will Allen and linebacker Justin Durant.Armstrong, a Carrollton Newman Smith product, visited the New York Giants earlier this week but opted to return to the Cowboys on a one-year, $630,000 contract.The Cowboys first signed him Nov. 26, and he played in one game before being released Dec. 22 to make room for Ronald Leary to be called up to the 53-player roster. The Cowboys re-signed Armstrong in January.Armstrong, 30, also played in five games with the Miami Dolphins last season, and he was with the Jacksonville Jaguars. He had 44 catches for 871 yards and three touchdowns for the Washington Redskins in 2010, making just 10 catches for 115 yards and two touchdowns since, none with the Cowboys.The Cowboys are $4.47 million under the $123 million salary cap.
