When the Indianapolis Colts placed quarterback Andrew Luck on injured reserve earlier this week, it wasn't a surprise. The $140-million star hadn't thrown in weeks, time was quickly running out on the season and they had worked out fill-in passers two days prior.

It was the expected outcome for a trying season that never got started -- and no one really knows what might come next.

Colts general manager Chris Ballard said Luck's injuries are not career ending, and Luck's statement was adamant: "I know I'll be better from this."

Over the past few weeks, Luck sought theories and second opinions from at least four doctors about his surgically repaired shoulder, per sources informed of the situation.

Based on interviews with several people involved in the situation, the picture becomes just a little bit clearer.

First, most recommendations have Luck taking a few months off from throwing -- likely two to three months to focus solely on rehab. At this point, no one has recommended another surgery, though it remains a possibility.

All parties believe Luck will be ready for the 2018 offseason.

The belief is that additional issues arose in Luck's shoulder, which are byproducts of playing through the torn posterior labrum for two years. That, not the labrum, has led to the setbacks.
