Former Colts defensive lineman Arthur Jones had sports hernia surgery three weeks ago, a source tells Ian Rapoport of NFL.com (on Twitter). He’ll need time to recover, so it is expected that he won’t be signing with a club until after Week 1, Rapoport adds. 
Jones has been on the market ever since the Colts cut him loose in March. The veteran came to Indianapolis on a five-year, $33MM deal prior to the 2014 season, but the deal wound up being a bust. In three years with the Colts, Jones played in just 17 combined regular season games, including a completely lost 2015 season. Between the so-so production, injuries, and a 2016 PED suspension, the Colts felt they had no choice but to cut their losses.
In eight games last year, Jones tallied 30 total tackles. When he was placed on IR in December, the advanced metrics at Pro Football Focus had him ranked as the No. 120 defensive tackle out of 126 qualified players.
After healing up, Jones is hoping to show teams that he can be more like the old version of himself. He is now far removed 2013 when he tallied 4.0 sacks and 53 total tackles while starting at defensive tackle for the Ravens.
