An article titled "Hulk Hogan lawyer tells SN: Gawker sex tape a 'massive' invasion of wrestler's privacy" has this:
Hogan's $100 million lawsuit against Gawker for posting a private video of him having sex with a friend's wife heads to trial at a Florida state court March 7. If Hogan (aka Terry Bollea) wins, Gawker could be ruined financially — or forced to sell.

In the last sentence, the past participle "fallen" is a perfect use, and I think you can start the sentence with "having" as follows:
Having now fallen on hard times after his WWE glory days, Hogan is looking forward to...
Am I right?
Is this dropping of "having" commonplace? Can such a dropping be done to other verbs than "fall"?
If it can, I'd like to have some examples of a perfect use of a past participle (other than "fall") without the auxiliary verb "have".
