The preseason trade for trouble Miami Dolphins corner Vontae Davis is starting to look like a huge dud for Colts owner Jim Irsay and general manager Ryan Grigson. Davis has battled injuries all season long, and when he has played he's been inconsistent.

Davis' most recent injury occurred during the Colts thrilling comeback win against the Titans in Week 8. Coach Bruce Arians told media he would know more on the availability of Davis for Week 9 against the Dolphins. However, if you talk to Davis directly (as Phil Richards of the Indianapolis Star did), his own prognosis is less optimistic:

"I'm going to be out a while," Davis said while crossing the locker room with a pronounced limp with a brace on his left knee. "Freak thing."

Davis had to deal with questions of dedication in Miami during his troubled tenure there. Now, in Indianapolis, "freak" injuries seem to be keeping him from playing.

The Colts surrendered a second round pick in the 2013 draft to get Davis. They've won three of their four victories without him playing for much, if any, of the snaps in those games. Safe to assume that, right now, Irsay and Grigson have buyer's remorse.

Positive news is Robert Mathis and Fili Moala could return to practice this week, per Richards.
