Kubiak collapsed and was carted off the field while walking into the locker room at halftime. According to Rapoport, Kubiak suffered a transient ischemic attack (TIA), which involves a loss of blood flow to a part of the brain, which leads to "temporary but reversible loss of function." Rapoport reported TIAs often have no residual effects and people who suffer them can recover quickly.
The Texans head coach was transported to a local hospital and was scheduled to undergo additional tests on Monday. The treatment he received on Sunday night was the same medical treatment used to treat strokes.
According to the American Stroke Association, a TIA is often called a mini-stroke and can be characterized as a warning stroke. It is caused by a clot, but the blockage is temporary, unlike a stroke. Most TIAs do not cause permanent brain damage.
