Frank Bush was promoted from senior defensive assistant to defensive coordinator on Tuesday, filling the biggest of three vacancies on the Texans' defensive staff. A second opening could be filled shortly.
Kansas City Chiefs secondary coach David Gibbs, son of Texans assistant head coach/offense Alex Gibbs, interviewed for the Texans' defensive backs coach position on Monday and Tuesday. The position was vacated when the Texans dismissed Jon Hoke on Dec. 30 along with defensive coordinator Richard Smith and defensive line coach Jethro Franklin.
"I had David in here yesterday and this morning," Kubiak said on Tuesday afternoon. "He went back to Kansas City. We had a very good visit. He's going to make a decision here probably over the course of the next 48 hours. He went back to visit with his family, so we'll see. It was very positive. We'll see what happens."
The search for a defensive line coach seems to be developing at a slower pace. Former Detroit Lions head coach Rod Marinelli interviewed with the Texans last week but opted to sign on as the associate head coach/defensive line with the Bears.
"I'm still kind of bouncing around," Kubiak said. "I had a couple of guys I was very interested in early. I had Rod come down and spend a day with me. Y'all know how much I think of him. I'm talking to another coach right now. I try not to get too many at one time. I'm trying to one at a time and see who's the best fit for the Houston Texans. It could take a while. It could happen in the next day or so. I'll keep you up to date."
