CLEVELAND (AP) - The Browns have signed steady center JC Tretter to a three-year, $32.5 million contract extension.

Tretter has started all 40 games since signing with Cleveland as a free agent before the 2017 season. The 28-year-old, who spent his first three NFL seasons with Green Bay, has helped solidify a Cleveland offensive line that lost 10-time Pro Bowl tackle Joe Thomas before last season and has struggled this year.

Tretter's deal includes $23 million guaranteed.

Browns general manager John Dorsey said Tretter "embodies all of the qualities that you look for in a football player."

Tretter didn't miss a snap last season despite playing with a severely sprained ankle, which limited his practice time and required daily treatments. With Tretter anchoring the middle, Cleveland's line did a solid job protecting then-rookie quarterback Baker Mayfield. He was only sacked five times in the final eight games.
