Broncos players were told at an 8 a.m. meeting today that Tim Tebow would replace Kyle Orton as the starting quarterback.

After this afternoon’s practice, head coach John Fox explained the decision.

“We’re a 1-4 football team. I’m a 1-4 head coach,” Fox said. “It’s my job, our job, to make decisions to try to change that. We’ll see if this is one that does that.”

Fox also made it clear that the Broncos’ 1-4 record is not all about who’s at quarterback.

“We haven’t gotten it done as a football team,” Fox said. “It’s not one guy, it’s not all Kyle Orton’s fault, but we do have to make adjustments, we do have to change, and we have to do something to win football games.”

The decision had expected since Tebow replaced Orton at halftime of the Broncos’ game Sunday against the San Diego Chargers. It had been previously reported that Fox would make the switch official when the team reconvened today.

The Broncos were down 23-10 at halftime when Fox yanked Orton at halftime and Tebow was informed by offensive coordinator Mike McCoy that he “was up.”

Tebow led the Broncos to two fourth-quarter touchdowns and had a final play pass into end zone knocked down in a 29-24 loss. The Broncos do not play this week so Tebow will make his first start of the season, fourth of his career, on Oct. 23 at Miami — where the Dolphins will honor former University of Florida football players.

There could be just as many Tebow fans, in other words, as Dolphin fans, in the stadium that day.
