In a move to deepen their special teams unit, the Texans signed fullback Boomer Grigsby on Tuesday. Grigsby is entering his fifth year in the NFL and has made a name for himself as a tenacious tackler on kick coverage. Grigsby began his career in Kansas City, where he was drafted by the Chiefs in the fifth round (138th overall) in 2005 out of Illinois State. Grigsby brings us a toughness that I like, special teams coordinator Joe Marciano said. He's a veteran special teams guy, hes had his bell rung a few times and he knows how to hit a guy. Im excited about working with him and getting him into our system. Source: Houston Texans.com
