The Pittsburgh Steelers have released veteran linebacker, and franchise sack leader, James Harrison.

The Steelers release Harrison, 38, to make room on the roster for right tackle Marcus Gilbert, who is returning from suspension.

Harrison’s agent, Bill Parise, said the parting is amicable. Harrison had become frustrated with his diminished role with the team.

“There was no animosity or bad feelings. It’s just the business of the NFL,” Parise told ESPN’s Josina Anderson. “I believe he still wants to play. We’ll have to wait and see what happens with waivers.”

“We’ll see what Santa brings us.”
