The Texans have signed safety Bernard Pollard to replace Chester Pitts on the roster.
Pitts, who underwent major knee surgery on Wednesday, was placed on injured reserve, meaning he's out for the season.
Pollard, 24, was Kansas City's second-round pick in 2006. He started 16 games last season for David Gibbs, who is in his first season as the Texans' secondary coach. Last season, Pollard had 84 unassisted tackles, and he was a surprise cut by the Chiefs in the last roster reduction this season.
Pollard, who is an excellent special teams player, got a lot of attention last season when he hit Tom Brady in the first game of the season, causing the New England quarterback to be lost for the season with a knee injury.
Pollard gives the Texans five safeties, counting Eugene Wilson, John Busing, Dominique Barber and Nick Ferguson.
