Allen Park — Lions defensive end Jason Jones was a limited participant in the team's offseason practices, but his absence from minicamp is supposed to help him be ready for training camp in August.
Jones underwent successful arthroscopic knee surgery this week, and even though the Lions won't rush him back, he's expected to recover by the start of training camp. Lions coach Jim Caldwell declined Thursday to provide specifics of Jones' injury.
"He had a little bit of an injury that he got taken care of, so he should be good," Caldwell said.
During the second week of organized team activities two weeks ago, Jones was on the sidelines for the practice open to the media. He participated in individual drills during the OTAs open last week, but was absent for all three days of minicamp this week.
The 29-year-old Jones had 22 tackles, five sacks, two forced fumbles and three passes defensed last season. He's expected to start again this year on the left side with Ziggy Ansah on the right side.
Jones tore the patellar tendon in his left knee in Week 3 of 2013, his first season with the Lions. He returned to play all 16 games in 2014.
"He'll be ready to go," Caldwell said when asked if Jones would be available for training camp in August.
Jones remained the only player absent Thursday. Offensive tackles LaAdrian Waddle (knee) and Cornelius Lucas (undisclosed) and running back Joique Bell (knee/Achilles) continued to sit.
