Tackle Bryant McKinnie was not at the Ravens' second full-team practice Friday, and the team still has not heard from him.
Head Coach John Harbaugh said on Thursday that there were some "issues" McKinnie is dealing with.
On Friday, he said he hasn't heard more than that.
"As far as I know there is no communication from Bryant," Harbaugh said.
"He does not have an agent. We heard from a chiropractor the first day and that's all we heard."
The chiropractor is the "representative" Harbaugh mentioned on Thursday. McKinnie did not report any back issues previously during minicamp, and was more focused on dropping weight.
Harbaugh also said the collective bargaining agreement applies to McKinnie's situation, meaning he is being fined for every day of training camp he misses. The fine is reportedly $30,000 per day.
Michael Oher, who has moved into McKinnie's left tackle spot in his absence, said he has talked to the big veteran. Oher said he thinks his teammate will be back.
"I think so. He sounds positive," Oher said before recounting some of their conversation.
"Like I told him, 'Take your time and we'll be waiting for you.' Take care of anything he has going on. I'm pretty sure he'll get everything squared away."
Rookie Kelechi Osemele moved into the right tackle position on Friday, splitting time with undrafted free agent Jack Cornell.
"Bryant McKinnie is missed because of the bond he's built with the other guys," Offensive Line Coach Andy Moeller said.
