Miles Austin going for MRI on hammy

Cowboys WR Miles Austin is going for an MRI on his injured hamstring on Monday.  The problem is with his right hamstring -- not the left one that hobbled him earlier this season.  "Randomly on that one play, my other hammy just grabbed up, out of nowhere," Austin said. "It's hard to describe how it feels, but it really hurts."  He missed 2 games with the first hammy injury, and expect him to miss at least 1 more with this one.  WR Laurent Robinson will move into Dallas' starting lineup while Austin is out.  He's worth adding as a stop-gap WR3 fantasy play.
