Texans signed DL Ricardo Mathews, formerly of the Colts, to a one-year, $730,000 contract.
A 2010 seventh-rounder, Mathews appeared in all 16 games last season, turning in 465 largely-ineffective snaps. Mathews has camped out at end the past two years, but has experience at tackle. He’ll compete for a spot as a rotational lineman.
