According to a report from NFL Network's Ian Rapoport, Texans head coach Gary Kubiak suffered a Transcient Ischemic Attack (TIA) at halftime on Sunday. The team would not confirm the report on Monday evening and had no further comment aside from a release sent out earlier in the day, in which GM Rick Smith said Kubiak was "alert, coherent and in good spirits."
Kubiak is still in a local hospital after collapsing on the field and being taken to the hospital in an ambulance during the Texans' 27-23 loss to the Colts. He will remain there until at least Tuesday.
According to the American Stroke Association, a TIA (also known as a mini-stroke) is caused by a clot. The difference between a stroke and a TIA is that the blockage is temporary.
From the American Stroke Association: "TIA symptoms occur rapidly and last a relatively short time. Most TIAs last less than five minutes; the average is about a minute. When a TIA is over, it usually causes no permanent injury to the brain."
Kubiak missed practice on Monday and defensive coordinator Wade Phillips ran it and the team meeting. Phillips has previous head coaching experience and would be a logical interim head coach if the team decides to go that route.
