ENGLEWOOD, Colo. — In short succession, the Broncos added a second defensive lineman Monday just after announcing the free-agent addition of nose tackle Domata Peko. Former Colts defensive end Zach Kerr also signed a two-year contract, joining the Broncos as their fourth free agent of the period since it opened on Thursday.

Kerr, who originally joined the Colts in 2014 as a college free agent, has played in 12 games in each of the past three seasons. He made his NFL debut in the 2014 season opener against the Broncos and later had a career game against Denver in 2016 with five tackles and one sack in Indianapolis' Week 2 loss to the Broncos.

In college, Kerr transferred from Maryland to Delaware, where he became a second-team All-Colonial Athletic Association player as a junior. That season, he had 27 tackles, 4.5 of which came from behind the line of scrimmage, and one sack. In his senior season, he more than double his tackle total with 57, had 5.5 tackles for loss, 3.5 sacks, four passes defensed and two forced fumbles.
