The Centre Daily Times reports the sign was left Monday outside Beaver Stadium.
A Penn State spokesman declined comment on the condition or location of the statue. University officials have said only that it is in a "secure location."
On July 22, 2012, just before 6 a.m., workers used jackhammers to remove the statue and took it away with a forklift. The statue had become a lightning rod for public opinion amid the sex-abuse scandal.
Paterno died in January 2012.
