Scout reported Friedgen's updated status yesterday on the LeGrand Stand message board with the expectation that he will not return.
Friedgen told reporters in November that his health would play a role in a decision to return, which is unlikely following National Signing Day.
Head coach Kyle Flood did not respond to a requested update on Friedgen's status. A teleconference is expected tomorrow with Flood at noon.
"Some things are a little tougher for me than others," Friedgen said in College Park, Md. "I'm going to sit back after the season and kind of reflect on everything.''
Friedgen, who is in his second year of a $500,000 deal, is the fifth offensive coordinator in as many years for Rutgers with Kirk Ciarrocca's 2009 and 2010 seasons as the last man to hold the job for more than one season.
Receivers coach Ben McDaniels would be the leading contender to replace Friedgen, joining the staff in 2014 after stints in the NFL with the Broncos and Buccaneers.
