Orr is a free agent after announcing earlier this week that he is looking to return to the NFL after a brief retirement. He sought additional opinions from doctors about his congenital neck and spine condition and believes he can play in the NFL again.
"There are a lot of variables that the Ravens are having to deal with," agent Rob Sheets told 105.7 The Fan in Baltimore. "There’s a lot of internal consternation. One side of the line fighting to get Zach Orr back, and another line saying we need to move on."
The Ravens issued a statement about Orr's comeback on Wednesday.
"I spoke with Zach [on Tuesday] and he informed me that he would like to continue to play football," general manager Ozzie Newsome said. "He is a free agent."
Orr is currently visiting with the Detroit Lions, and he will meet with another team Friday, according to Sheets. There are three other visits scheduled for next week.
"We’ve spoken to 15 teams," Sheets said. "In essence, half the NFL is curious to do their own 'due diligence'."
Orr, 25, led the Ravens last season with 132 tackles in his first season as a starter. He also had three interceptions, a forced fumble and two fumble recoveries.
Ravens players have been lobbying on social media for Orr to return to Baltimore.
