Defensive end Jason Jones was absent from all three days of the Detroit Lions' mandatory minicamp this week. Lions head coach Jim Caldwell simply said that Jones was excused from the minicamp on the first two days of practice, but he revealed the true nature of Jones' absence on Thursday. From MLive:
"He had a little bit of an injury that he got taken care of," Caldwell said. "So should be good."
Caldwell didn't get into the details of Jones' injury, but The Detroit News reports that Jones "was expected to undergo arthroscopic knee surgery this week." Caldwell even declined to confirm that Jones underwent surgery, instead suggesting that he simply underwent a procedure.
Asked Jim Caldwell about Jason Jones, said the DE underwent a procedure. Stopped short of calling it a surgery, though.— Kyle Meinke (@kmeinke) June 18, 2015
Whatever word you want to use to describe it, Jones clearly had something done to repair an injury that forced him to miss some time during OTAs. It's never good for a veteran player who has dealt with a serious knee injury in the past to suddenly have a procedure or surgery this late in the offseason, but better to fix the issue now than let it linger, I suppose.
As far as a timetable goes for Jones' return, Caldwell merely indicated that Jones should be ready for the regular season. Given how the Lions have handled injuries under Caldwell, I would expect them to bring Jones along slowly during training camp in order to make sure he's 100 percent healthy before he returns to the field.
