Second stint with Saints
The Saints brought Olsen back for a second stint with the team on October 22, 2014. He was expected to provide additional depth on the line after an injury to Jonathan Goodwin meant that backup center Tim Lelito would be starting. He was released on November 12, 2014.
Second stint with Titans

Olsen has one brother, Drew, a former safety at Gettysburg College. His father, Andy Olsen, was a New York City firefighter. Just three days before the 9/11 attacks, his father was promoted to Lieutenant. Therefore, he was in officer training on September 11, and not with Ladder 80, his firehouse at the time. When his father finally arrived at the World Trade Center site, both towers had already collapsed. A few days later, when he was digging through the rubble, his father found a truck from his firehouse buried and destroyed. None of the firefighters in that particular unit survived.
