CHARLOTTE -- With many still wondering if Michael Oher will be at next week's mandatory minicamp, the offensive tackle may have hinted at the answer on Instagram Thursday night with a picture that was posted and quickly deleted.

On Friday, Panthers general manager Dave Gettleman made clear his concern about Oher, who's been in the NFL's concussion protocol for more than eight months.

"I don't know if Michael posted that photo or not," Gettleman said. "Regardless, my primary interest is Michael's health."

On May 5, Gettleman flew to Nashville to meet with Oher because Gettleman had not spoken to Oher since early March.

"We really had a great visit. We talked for an hour, had lunch, it was a very comfortable conversation. We talked about a lot of things – nothing about football. It was about him, how he was doing and the issues he was dealing with," Gettleman said. "It started and ended well. And after we met, Michael did follow up for a few days. However, the communication has stopped.
