Update: Mike Klis of the Denver Post is reporting that Decker's injury is not as bad as originally thought:
Decker suffered an sprain of his medial cruciate ligament (MCL) and will undergo an MRI on Monday in Denver. The injury wasn't as serious as the Broncos first thought, the team said after the game.
Decker started the game, but was taken out by a vicious hit to the knee from Steelers' linebacker James Harrison.
Decker had to be helped off the field by trainers and rotoworld.com has reported that the Broncos have confirmed that he will not be returning to the game.
This is a huge loss for Denver, as they are going up a stellar Pittsburgh defense.
The catch is, as of right now the Broncos are having a pretty easy time moving the ball through the air, and Tebow has already notched one touchdown pass.
Either way, Decker is a big part of the Broncos offense and he will undoubtedly be missed.
The real story will evolve if the Broncos actually do beat the Steelers though.
What is the extent of the injury? Will Decker be able to play in the second round?
Those are all questions that are left unanswered, but right now they hinge on the play of the rest of his teammates.
The Rotoworld report states that Eddie Royal will be filling in for Decker, who was the recipient of Tebow's touchdown throw.
Decker left the game with just one catch for nine yards.
