Bell can be seen in the video doing drills and cutting on the knee.
It is not known if Bell will be a full participant in the team’s OTA’s scheduled for the end of May and the mandatory minicamp which starts June 16.
Bell will miss the first three games of the 2015 season after being suspended without pay for violating the league’s substance abuse policy. He was arrested for marijuana possession and driving under the influence while headed to an airport with former Steelers running back LeGarrette Blount before a preseason game last year.
The Steelers running back is scheduled to make his season debut in the team's Week 4 game against the Ravens. Pittsburgh opens their season on Sept. 10 against the defending champion Patriots.
Bell ran for 1,361 yards with eight touchdowns and also had 83 receptions for 854 yards and three scores last season while earning his first Pro Bowl berth and receiving first-team AP All-Pro honors.
