It was the second move made by interim general manager Marty Hurney since being hired Wednesday. Earlier in the day, he gave right guard Trai Turner a four-year, $45 million extension with $20.45 million guaranteed.
Oher tweeted Thursday after his release that the "brain is a scary thing."
The Brain is a scary thing. You have to be careful with it.

Oher, 31, is guaranteed $900,000 as part of injury protection benefits. His release saved the Panthers $1.69 million toward the salary cap. He had three years remaining on his contract after signing an extension last season.
"The most important thing is his health," Panthers coach Ron Rivera said, according to the team's website. "Michael's health always came first. We were not going to force the issue. Michael understood and we expressed that to him."
Oher had planned to report to training camp, a league source told ESPN last week, but his future with the team remained in doubt because of the concussion.
Oher was a first-round draft pick in 2009 and played in two Super Bowls, winning a championship with the Baltimore Ravens in February 2013. He was best known because his life story was the catalyst for the 2009 movie "The Blind Side," starring Sandra Bullock.
Oher is set to appear in a Nashville, Tennessee, court on Friday. He faces a misdemeanor assault charge, stemming from an altercation with an Uber driver in April.
Earlier this week Oher defended former Panthers general manager Dave Gettleman, who was fired Monday.
Oher joined the Panthers in 2015 and started all 16 regular-season games at left tackle during a 15-1 season and run to the Super Bowl. He started the first three games of the 2016 season before going into the concussion protocol.
