The Pittsburgh Steelers made another set of transactions on Wednesday as wide receiver David Nelson and running back Braylon Heard were signed to the roster. To make room for both players on the 90 man roster, running back Cameron Stingily was placed on the waived/injured list and kicker Shaun Suisham was placed on the Reserve/Injured list.

Stingily tore a ligament in one of his knees Sunday night in the preseason opener against the Minnesota Vikings. He had originally signed with the Steelers as an undrafted free agent out of Northern Illinois.

Suisham also tore the ACL in his left knee Sunday night and is now out for the season. Both players had surgery Wednesday morning.

Nelson entered the league with the Buffalo Bills as an undrafted free agent in 2010. He has also spent time on the rosters of the Cleveland Browns and New York Jets. He has registered 138 catches for 1,530 yards and 10 touchdowns during his career. He measures in at 6052.

Heard, a rookie undrafted free agent out of Kentucky, rushed for 368 yards and 4 touchdowns on 73 carries last season. He also caught 21 passes for another 108 yards. At the 2015 combine, Heard registered a 4.63 second time in the 40-yard dash. He measured in at nearly 5’10”, weighed 198 pounds. At his March pro day, Heard ran the 40 in 4.57 and 4.53 seconds. He spent the 2011 and ’12 seasons at Nebraska, where he rushed 77 times for 452 yards, a 5.9-yard average carry, and one touchdown.

Nelson will wear No. 15 while Heard will wear No. 40.
