The Bengals signed the nine-year veteran to a two-year contract extension Thursday.
"Domata has been a significant and productive player for our defense for many years now, and we are excited to extend his time here even longer," said Bengals head coach Marvin Lewis in a press release. "He is a leader among our veterans and a mentor for our younger players, and securing his future as a Bengal through the next three seasons is another positive step in continuing to improve our team."
Peko was selected by the Bengals in the fourth round of the 2006 draft. He has become a mainstay on the line, starting all of the team's games at nose tackle last season to amount to a streak of 67 straight starts. In 2013, he notched 72 tackles and a career-high three sacks.
