The Broncos fortified their offensive line Monday by signing tackle Ryan Harris, who was a three-year starter in Denver from 2008 to 2010.
The Broncos, who are preparing to face the Pittsburgh Steelers in a wild-card game this weekend, lost guard Chris Kuper to a broken leg in Sunday's loss to the Chiefs. Kuper was placed on season-ending injured reserve.
"He's a real big loss," Broncos rookie right tackle Orlando Franklin said of Kuper. "He definitely was the bus driver on my side. He was making all the calls and whatnot. Russ (Hochstein) stepped in and did a good job (Sunday)."
Harris was drafted by the Broncos in 2007 and became a starter the following year. He was signed by the Philadelphia Eagles, but he hurt his back last summer and reached an injury settlement with the team.
