"We have lost a bright light in our beloved brother, Konrad Reuland," tweeted his alma mater, Stanford University. "His memory and spirit will never leave us. We love you. #RIPKonrad."
Reuland suffered the aneurysm on November 28 and underwent surgery the following day.
Baltimore coach John Harbaugh announced Reuland's death on Monday, saying, "We lost a Raven today," according to ESPN.
"I just want to offer condolences to his family. We love Konrad Reuland. Every single guy in the locker room loves him," he added.
Before joining the Ravens, Reuland played with the Jets for the 2012 and 2013 seasons.
Our thoughts and prayers are with his family and friends.
