Denver Broncos lineman Tyler Polumbus announced his retirement on Facebook Tuesday.
The Cherry Creek High School and University of Colorado Boulder football player was an undrafted rookie when he signed with the Broncos in 2008.
Polumbus played two years with the Broncos, then spent time with Seattle (2010-11), Washington (2011-14) and Atlanta (2015), before returning to the Broncos last fall .
After the Super Bowl victory, Polumbus decided to retire.
"In 2008 Liz and I began the journey of a lifetime. 8 years and 4 teams later we feel that it is time to call it a career in the NFL," Polumbus wrote on Facebook. "When this journey began I was just hoping that I could make the team with extremely long odds in front of me as an undrafted rookie. I thought it would be amazing to say that I played a season or two with the Denver Broncos. I never imagined that God would keep opening door after door for me to continue in this game. I am incredibly grateful for His mercy, grace, and blessings He has given my family."
Polumbus' Facebook post thanks the Broncos and the other teams he played for.
"Thank you to the Denver Broncos for giving me the opportunity to win a Super Bowl with the team I grew up rooting for. The Seattle Seahawks, the Atlanta Falcons, and the Washington Redskins organizations, you will forever be part of the Polumbus family," Polumbus wrote.
He thanked coaches, family and fans. Read the entire letter here .
