DENVER— Gary Kubiak is headed home from the hospital, but don't expect to see him back on the football field this week.

John Elway announced Monday afternoon Gary Kubiak will have the week off from coaching. Joe DeCamillis will be the team's interim head coach.

Broncos coach Gary Kubiak was released from a local hospital Monday afternoon after he was taken there by ambulance about 45 minutes after his team suffered its first loss of the season Sunday to the Atlanta Falcons.

According to the Broncos, Kubiak underwent several precautionary tests at the hospital, including an MRI and CT scan. Both tests came back normal.

Kubiak was diagnosed with a complex migraine condition that caused extreme fatigue and body weakness.

The team says he received medication and is feeling much better.

As for quarterback, the Broncos are hoping Trevor Siemian recovers sufficiently from his left shoulder injury to play Thursday night against the San Diego Chargers in San Diego.

“I think a possibility for sure,’’ Siemian said following the Broncos’ 23-16 loss Sunday. “I’m one day better. I get in tomorrow and see what Greek tells me but I’m feeling better and better.’’

Greek is Broncos’ head trainer Steve Antonopulos who received an unexpected patient Sunday evening in his head coach. Kubiak collapsed at halftime of a game in 2013 when he was the head coach of the Houston Texans. He was later diagnosed as having a transient ischemic attack, or a mini-stroke.

Kubiak later blamed the episode on “running himself into the ground.’’ He was in the midst of an 11-game losing streak then. He had the stress of breaking in a rookie quarterback for his first NFL start last week. Paxton Lynch was only 6 of 14 for 91 yards with an interception (35.1 passer rating) and three sacks as the Broncos fell behind, 20-3 midway through the third quarter. From there, Lynch was 17 of 21 for 132 yards and a touchdown (108.7 rating) with three more sacks.

“I thought he did well,’’ said Siemian, who watched the game from the sidelines. “Atlanta’s got a good D-line. He got banged around so I thought he did well. Obviously there’s things we’ve got to do better on offense. So obviously we can clean that up.’’

Asked if he was frustrated to have watched the game out of uniform, Siemian said: “Yeah I think as a competitor you want to be out there every time with the guys. So that part of it stinks.’’
