Trystan Colon

Lions signed OG Trystan Colon, formerly of the Cardinals, to a one-year contract.

The move gives Detroit some interior offensive line depth following center Frank Ragnow’s abrupt retirement. Colon started seven games at right guard for the Cardinals last season. He previously made starts at left guard in Arizona and earned a handful of spot starts at center while in Baltimore. His addition will create some flexibility in the trenches for Detroit even if he doesn’t win a starting job in camp.
