Seattle and Houston also put in claims on Polumbus, but the Lions were awarded the player based on having the worst record in 2009 out of the three teams.
"It was a little unexpected," Polumbus told the Denver Post. "But I'm just blessed to have been able to start my career here in Denver in my hometown."
At 6-foot-8, 320 pounds, Polumbus is familiar with the zone blocking scheme, having played for Seattle Seahawks offensive coordinator Jeremy Bates while in Denver.
The Seahawks still could be in the hunt for Polumbus, however. The Lions are reportedly deep at tackle, and Seattle and Detroit have been active trade partners over the last, two years.
The Seahawks are looking to beef up their depth at tackle with starter Russell Okung (ankle) and Ray Willis (knee) out.
