Jason Jones was one of the Tennessee Titans' priorities to retain this off-season, as the club talked about the possibility of moving back back to defensive tackle after a season at end.

However, it appears Jones is poised to test the free agent market, according to TitanInsider, after the Titans met with the defensive lineman's representatives this weekend at the NFL Combine in Indianapolis.

Jones has 15.5 sacks during his four-year career with the Titans and recorded three sacks in 2011.

The two sides are still expected to negotiate, but an extension before free agency begins March 13 now appears less likely. One potential problem area appears to be how to compensate Jones - as a tackle or as an end.
