Tyler Clutts served as the Cowboys’ fullback since late in the 2013 season, but he is a free agent.
Keith Smith has been on and off the active roster the last two seasons. He was credited with two special teams tackles last year. At 6-foot, 232 pounds, he has the build for the position. He wore No. 56 last year and now wears No. 41.
Rod Smith joined the Cowboys off waivers last year from the Seattle Seahawks. He played in 10 games but did not have a carry or a catch. He also played special teams. At 6-foot-3, 226 pounds, he has a different frame for than a traditional fullback, but the Cowboys like his versatility.
He is the older brother of the team’s second-round pick, linebacker Jaylon Smith.
The Cowboys also have Tulsa fullback Mandel Dixon at this weekend’s rookie minicamp on a tryout basis.
