Patriots cornerback Jonathan Jones has not practiced for two weeks.

Or, for that matter, even been spotted near a football field.

Jones was last seen at an in-stadium practice on Aug. 4, when he wore street clothes and walked the sideline. Prior to that night, he had been a staple of the Patriots’ top defense during team periods in training camp. Jones again projects to start this season, after logging 16 starts, 69 tackles, four interceptions and three forced fumbles last year.

The Patriots have not announced whether Jones is injured, but cornerbacks coach Mike Pellegrino indicated Friday he’s been with the team.

“He’s doing the best he can, and he’s trying to get better every day. I love Jon. Jon’s in the room, he’s like a second coach in there,” Pellegrino said. “Every time we’re talking, he can always add in an extra piece of advice in the meeting room.”

Several injured Patriots, including offensive linemen Mike Onwenu and Cole Strange, have popped by recent practices, occasionally in uniform. Onwenu attended both joint practices in Green Bay this week. Asked for clarification about whether Jones is in Green Bay, Pellegrino dodged.

“Uh, sometimes,” he said. “Sometimes not.”

Pellegrino then added: “Not here. Might be here.”
