Marinelli, who was in Houston on Thursday, told KRIV-TV that "it was a great visit."
Marinelli's specialty is defense. The Texans need a defensive coordinator, a defensive line coach and a secondary coach.
Marinelli, who was reached at Bush Intercontinental Airport before flying home to Detroit, didn't indicate when the Texans said they would be in contact with him again.
