Injuries have forced the Steelers to make several roster moves, with two players signed and two placed on the reserve/injured list.
Offensive lineman Jerald Hawkins and tight end Jake McGee are both out for the season after suffering injuries during the team's OTA session on May 30. Both players were hurt in practice and are now on the reserve/injured list.
The team added offensive tackle Bryce Harris and tight end Ryan Malleck to the offseason roster to fill the voids, signing both players to one-year contracts.
Harris came into the NFL as an undrafted rookie free agent, signed by the Atlanta Falcons in 2012. He was released before the start of the regular season and signed to the Falcons practice squad. The New Orleans Saints signed him off the practice squad to their active roster. He made his NFL debut against the San Francisco 49ers, but was injured in the game and placed on injured reserve.
Harris, who has played in 39 games with four starts, has bounced around, with the Steelers his seventh NFL team. He had two stints with the Falcons, three with the Saints, and also spent time with the Jaguars, Dolphins, Lions and 49ers.
Malleck is familiar to the Steelers after he spent time on the team's offseason roster last year, signed in February, but released in mid-May.
Malleck also entered the NFL as an undrafted rookie free agent, signing with the New York Giants in 2016. He was waived/injured by the Giants before the start of the 2016 season.
After the Steelers released him last offseason he was signed by the Baltimore Ravens, with a short stint on their practice squad. He was signed to the Houston Texans practice squad last November and placed on their active roster in late December. The Texans waived him this offseason.
