Jones has been playing through a shoulder injury, but Gase told reporters that he wasn't sure if an injury played a role in Jones' departure from the playing field.
"I haven't asked a whole bunch of questions because we were having our own issues on the other side of the ball," Gase said. "It will be one of those things where I'll probably learn a little more tonight and try to figure out what's going on."
Jones did not return to the locker room and remained on the sidelines without his helmet, according to ESPN.
Veteran Cameron Wake spent time with Jones whenever the defense wasn't on the field, but Wake didn't elaborate on any discussions, including whether the safety is healthy, between the two.
And whatever happened Sunday with Jones' departure from the game will remain a mystery for now until either Jones or Gase provides an update in the coming week.
As to whether Jones will be available for Week 10's game against the Green Bay Packers, Wake didn't appear concerned.
"Unless you know something I don't know, I don't see why not," Wake told reporters.
UPDATE: Gase addressed Jones' status when meeting with the media Monday morning.
