Bell attended Greenville High School, where he played offensive tackle for the Lions football team.

[3] As a rookie, he was named the starter at right tackle in the second game after Jeff Otah sustained a concussion in the season opener.

He returned to a backup role until the seventh game, when Otah was placed on injured reserve because of a knee and back injury.

On April 22, 2015, he was signed as a free agent by the Tennessee Titans, to provide depth in the wake of Michael Roos' retirement and Taylor Lewan's move to left tackle.

He began the regular season as the Cowboys' backup swing tackle, until Chaz Green returned to that role after being passed on the depth chart at left guard by Jonathan Cooper in the sixth game against the San Francisco 49ers.

In Week 9 against the Atlanta Falcons, he replaced Green in the third quarter at left tackle, who up to that point had allowed five sacks to defensive end Adrian Clayborn.

Bell allowed one more sack, even though the Cowboys coaches were criticized for not adjusting their game plan to stop Clayborn.

[7] Green would not recover from the debacle and did not play another snap for the rest of the year, with Bell starting the last 2 games at left tackle in place of an injured Tyron Smith.
