The move was made to create room for Kelly Johnson on the club's 40-man roster. Johnson accepted arbitration prior to Wednesday night's midnight ET deadline.
Jeroloman spent the vast majority of the 2011 season with Triple-A Las Vegas, hitting .240 with two homers and 26 RBIs in 79 games. He was called up to the big leagues in late August, but the 26-year-old was unable to get into a game during the final six weeks of the season because of a previously undisclosed hand injury.
"We just waited to announce it because we wanted to get a hold of Brian first," Blue Jays general manager Alex Anthopoulos said of the move. "It's someone we had to take off the 40, and we had to do it right now. Because of the Rule 5 [Draft], we weren't allowed to outright him [to the Minors]. So we DFAd him, put him on outrights, and we'll see if he clears."
