Houston Texans head coach Gary Kubiak was released from the hospital Tuesday, but is not expected to return to the team for at least one week.
Kubiak spent two nights in the hospital and a series of tests Monday determined he experienced a "mini-stroke" Sunday night.
"I want to thank my family, the McNair family, the Texans organization, the doctors and staff at Houston Methodist and the entire Houston community for all the love and support we have received over the past three days," Kubiak said in a statement. "I've been through an ordeal and my focus now is to get back to good health. Doctors have told me I will make a full recovery but we have not determined when I will be cleared to return to the office. Again, thank you for the support and concern."
Kubiak collapsed while jogging off the field toward the locker room at halftime during the Texans' game Sunday night against the Indianapolis Colts at Houston's Reliant Stadium.
He was found to have experienced a transient ischemic attack (TIA), also known as a mini-stroke. During a TIA, a blood clot temporarily blocks an artery and restricts blood flow in the brain. A TIA usually does not cause permanent brain damage, though it is viewed as a possible precursor to a more serious stroke.
According to ESPN.com, Kubiak received intravenous tissue plasminogen activator, which is prescribed to break up blood clots.
Kubiak's family said he was "feeling good," Monday morning.
Kubiak, 52, collapsed but was able to sit up and respond to medical personnel on the Reliant Stadium field. He laid on his back to be stabilized before being lifted to the stretcher.
Defensive coordinator Wade Phillips replaced Kubiak in the head coach role for the Texans and will operate in that capacity until further notice, the team confirmed. There is no official timetable for Kubiak's return. The Houston Chronicle reported Tuesday that Kubiak would miss one game.
Phillips has experience as a head coach, most recently with the Dallas Cowboys.
His father, legendary NFL coach Bum Phillips, died Oct. 18.
The Texans lost Sunday's game 27-24, squandering a 21-3 halftime lead.
Kubiak is in his eighth season as the Texans' coach. The team is off to a 2-6 start this year, dropping his coaching record to 61-59. Kubiak played nine seasons as an NFL quarterback, all for the Denver Broncos, backing up John Elway from 1983-91.
