The move by Worldwide Wrestling Entertainment has prompted allegations that a racist audio tape is the reason behind Hogan's removal.
Sources say they have seen transcripts of yet-to-be-released audio in which Hogan uses racist terms, and which some reports suggest refer to fellow wrestler Dwayne "The Rock" Johnson.
American journalist Marc Lamont Hill tweeted: "...the transcripts that I've seen have Hogan calling The Rock the 'N-word' and 'sambo' among others."

With rumours as yet unconfirmed by WWE, an older clip of a controversial interview by Hogan has re-circulated online.
Hulk Hogan is the iconic wrestling figure of the 20th century, perhaps the biggest ever. For the WWE to disappear him is a BIG DEAL.— Marc Lamont Hill (@marclamonthill) July 24, 2015ADVERTISEMENT
The Internet is saying that Hulk Hogan has been recorded saying something so racist that WWE has scrubbed every mention of him from its site— Andy Khouri (@andykhouri) July 24, 2015
Holy hell, Hulk Hogan is wiped from WWE all together. Like vanished. Rumor is audio of him going on a racist tirade is to blame.— Cullen J. (@Cullenmon) July 24, 2015
View video of the 2012 interview, which aired on Eminem’s Sirius XM hip-hop channel Shade 45, below.
However, as this interview is historic, it is not thought that it is the audio reported as being close to being released.
World Wrestling Entertainment’s Hall of Fame was amended to remove Hogan and he has been left off a list of judges for the current Tough Enough competition series.
Wrestling correspondents were quick to spot the changes to the website.
Hogan's final fight in the Wrestlemania series is also now in doubt.
The video of the three-year old interview began re-circulating online and on websites including the Daily Motion.
However, the reason for the changes to the WWE website have yet to be confirmed.
British representatives of WWE declined to comment when contacted by The Huffington Post UK.
Meanwhile Hogan has tweeted a somewhat cryptic message.
In the storm I release control,God and his Universe will sail me where he wants me to be,one love. HH— Hulk Hogan (@HulkHogan) July 24, 2015
