Kubiak, who returned to work on Monday, spoke to reporters on Wednesday for the first time since collapsing on the field at halftime in Houston's loss to Indianapolis on Nov. 2.
"I just don't remember a whole lot," said Kubiak. "I remember right before the half not feeling very good. I had a headache. That's about the last thing I remember. Then I was at the hospital talking to different people."
He says that doctors have limited his work this week, but that he will lead the team when the Texans try to break a franchise-record seven-game losing streak against the Raiders.
After his health was discussed, the talk turned to safety Ed Reed. The future Hall of Famer was released Tuesday.
"I talked to Ed yesterday," said Kubiak. "We're playing young guys and we really like the way DJ (Swearinger) is playing and Shiloh (Keo) is playing and his role became diminished, especially the last few weeks. In all fairness to him, like I told him, in respect to his career and what he's done and when we're playing him 8 to 10 plays and that was going to do it right now, I thought it'd be fair for him to give him an opportunity to play somewhere else."
Kubiak also addressed the play of some the Texans, specifically JJ Watt, Andre Johnson and Ben Tate, who he said have given it up for the team. He mentioned that running back Arian Foster, who was placed on injured reserve Tuesday, will have surgery tomorrow. As for quarterback, he says it's still week to week whether it's Case Keenum or Matt Schaub. He said Schaub is itching to get back out there.
