Cowboys lock up center Frederick on long-term extension

IRVING, Texas (AP) — The Dallas Cowboys have locked up center Travis Frederick with a long-term contract.

The Cowboys signed the two-time Pro Bowl player to a six-year, $56 million extension that runs through 2023 after agreeing to terms just before the preseason opener at the Los Angeles Rams on Saturday. The average of $9.1 per season makes him the NFL’s highest-paid center.

Frederick, drafted 31st overall in 2013, was the second of three first-round picks on the offensive line by Dallas in a four-year span starting with left tackle Tyron Smith in 2011. Left guard Zack Martin was the team’s top selection in 2014.

Smith is also signed through 2023, and an extension for Martin is likely to be an issue next summer.
