It's every running back's worst nightmare: lingering and ongoing knee issues. Knowshon Moreno is currently dealing with that nightmare and now, according to Omar Kelly of the South Florida Sun-Sentinel, Moreno won't be playing in the NFL for all of the 2015 season -- all because of his knee.

Knowshon Moreno - Week 6 vs. Green Bay
Knowshon Moreno has a chance to return this week, although reports on Thursday may lean towards him not playing. He's apparently uncomfortable wearing an arm brace and his playing status may be determined by whether or not he needs to wear it.
Before his injury, Moreno looked like a great back to have. He ran 24 times in Week 1 for 134 yards and a touchdown. He appeared to be ahead of Lamar Miller, but with his injury the positioning may have changed.
There are a lot of question marks surrounding Moreno this week, making him a risky play. He's at best a flex option in a favorable matchup against Green Bay.
