The Cardinals signed Martin (undisclosed) to a contract Friday, Matt Zenitz of CBSSports.com reports.
Martin was one of four players who the Cardinals hosted for a tryout Friday, and the team was impressed enough to sign the Western Kentucky product. Martin has appeared in only six regular-season games since being selected by the Lions in the third round of the 2023 NFL Draft. He'll have the opportunity to compete for a depth spot at defensive tackle behind presumptive starters Walter Nolen and Roy Lopez.
