(KPRC) -- Houston Texans head coach Gary Kubiak suffered a transient ischemic attack, also known as a mini-stroke, when he collapsed on the field during halftime of Sunday night's game, according to NFL.com.

Kubiak will remain hospitalized for at least the next 24 hours after he collapsed Sunday on the field, according to the Houston Texans.

The team said Monday morning Kubiak is in the company of his family and under the care of physicians and staff at a local hospital.

Kubiak collapsed leaving the field at halftime of the Texans' game Sunday night against Indianapolis and was taken by ambulance to a hospital.

According to the team, Kubiak experienced dizziness and a light-headed feeling as the team made their way into the locker room Sunday night. He hunched over and dropped to his knees at the 24 yard line and was immediately surrounded by medical personnel. He was lifted off the field on a stretcher and taken by cart to the ambulance.

"Our primary concern is of course with Gary's health and well-being," Texans Executive VP of Football Operations and General Manager Rick Smith said in a statement on the Texans' website. "There have been so many people throughout the city and across the country that have reached out to express their love and support and we are thankful for everyone's thoughts and prayers. Gary is alert, coherent and in good spirits. He is continuing to be evaluated and monitored."

Texans defensive end Antonio Smith said, "When I seen it happen I was real worried but I prayed on it so I have no worry in my heart. I know he's gonna be alright we're just waiting for him to get back here."

"They may want to do some additional tests," said Dr. Puneet Patni, of the Kelsey Seybold Clinic.

He is not involved in Kubiak's care, but said there are certain things to check in a case like this.

Dr. Patni said, "You would want to evaluate someone's sudden collapse or briefly passing out for a lot of potential causes other than dehydration or in addition to dehydration and that would include, immediately after the event, doing an EKG, checking blood sugar, checking his vital signs, doing a thorough medical exam."
