Fraser has been MRP chairman since 2010.
Fresh from his first season at League headquarters, football operations manager Mark Evans is expected to conduct a wide-ranging review of the points system for on-field indiscretions and the two-step panel-to-tribunal process.
"We don't know … hopefully yes, but we'll see," Fraser told The Verdict on AFL.com.au when asked if he'd return in 2014.
"Not sure at this stage, obviously there's a review that happens with the MRP at the end of the year, and they'll decide whether we continue on or not."
Fraser said the decision was in Evans' court.
"He will be conducting a review of how things have been running and whether he wants to change anything and then we'll see what happens from there."
Fraser played 45 games for Collingwood and 65 for Essendon before reaching as high as AFL level as a field umpire.
Evans replaced long-time football operations manager Adrian Anderson at the start of this year.
Anderson oversaw the implementation of the current tribunal system in 2005.
