The Steelers agreed to a one-year contract with free agent linebacker Steven Johnson on Friday, giving the team depth at the position.

"I am very excited," said Johnson. "Growing up in Eastern Pennsylvania, being a diehard (Philadelphia) Eagles fan growing up, you always knew about the Pittsburgh Steelers, the Steel Curtain and the great defense. I am very excited to be a part of this organization and I am looking forward to it."

Johnson spent the 2015 season with the Tennessee Titans, playing in 16 games and recording seven tackles.

Johnson was originally signed as an undrafted free agent by the Denver Broncos in 2012, and spent his first three seasons with the Broncos. He played in 41 games for the Broncos, starting six, and had 50 tackles in three seasons.

He played in 57 games during his career with a total of seven starts, and has played in five postseason games with one start.

The fifth-year linebacker has made his mark on special teams during his career with 34 special teams tackles, three fumble recoveries and one forced fumble.

"On special teams you are going to get a guy who is like a Tasmanian Devil out there, trying to make plays, just doing what the coach wants me to do," said Johnson. "On defense you are going to get the same thing, a guy who is going to fly around and make plays. That is what it's all about. Defense wins championships and special teams are the unsung hero."

Johnson, who took to Snapchat when he saw the team's six Super Bowl trophies, said the tradition was part of what made joining the Steelers so attractive.

"I am looking forward to coming in and putting my best foot forward and helping this team win another one of those Super Bowls you have out there," said Johnson.  "That is something I want to be a part of. Coming here and seeing the tradition and history, I had a good feeling about it. I wanted to be a part of a winning organization because I am a winner. I wanted to be a part of a championship team. I want to come here and contribute any way I can."
