Reliant Stadium was in a frenzy, a proverbial hornet's nest, and the Colts were virtually powerless to stop it.
Houston's defense was harassing Colts' quarterback Andrew Luck. Screen passes weren't even slowing down the Texans' pass rush. Reggie Wayne's absence was felt as well. When Luck was able to get a pass off, his receivers weren't as sure-handed as they needed to be at times.
Case Keenum was marching the offense up and down the field and connecting with Andre Johnson with relative ease as Houston raced to a 21-3 halftime lead.
He was taken to the hospital and treated for stroke-like symptoms.
Suddenly perspective was shifted. Climbing back into the thick of the AFC South race wasn't nearly as life or death as it was when the ball was kicked off.
Kubiak's well-being rightfully took top priority.
John McClain of the Houston Chronicle provides more insight.
These coaches grind and grind and no one has a second thought about it until something like this happens. Players, coaches and fans alike become consumed with the season.
The ironic thing about Kubiak and Fox is that both of their issues occurred on or around the bye week. Fox and the Broncos are on their bye week, Kubiak and the Texans had theirs the previous week.
Resting and recharging the batteries wasn't quite enough to undo all the wear and tear they had put themselves through in the weeks leading up to the bye.
When the second half resumed, things were noticeably different for obvious reasons. Defensive coordinator Wade Phillips assumed the head coaching duties.
Offensive coordinator Rick Dennison called the plays.
Indianapolis rallied to win 27-24.
Give the Colts credit, they made the plays that needed to be made to win.
However, there was no way the Texans couldn't be affected by seeing their head coach leave the field on a stretcher.
If any team knows about watching their head coach face adversity it's Indianapolis. Chuck Pagano had an extensive battle with cancer last season.
That said, Kubiak's situation was different in that it happened suddenly while the game was in progress.
It was just a sad evening all the way around.
They all pale in comparison to losing a game that the head coach had to leave at the half.
Hopefully Coach Kubiak makes a full and speedy recovery.
