The Eagles signed defensive lineman Mike Martin to a one-year contract on Tuesday.
Martin, 25, was a third-round pick by Tennessee Titans in 2012 out of Michigan. He played the past four seasons with the Titans, starting five games and appearing in 68. He has career totals of 42 tackles and four sacks.
At 6-foot-1 and 298 pounds, Martin will compete for a depth spot at defensive tackle. The Eagles already lost Cedric Thornton in free agency this offseason, and Martin is the only newcomer at the position. Fletcher Cox and Bennie Logan are expected to be starters, and Beau Allen and Taylor Hart both return from last season.
