Texans offensive tackle Seantrel Henderson's $4.5 million contract provides plenty of protection in case the veteran blocker isn't healthy.
Henderson is due a $1.5 million base salary, but just $1 million is guaranteed for skill, injury and salary cap. The injury guarantee doesn't apply to preexisting injuries.
Henderson spent all but one game last season on injured reserve with a broken ankle.
