Nick Hogan is speaking out for the first time since his car crash Sunday in Florida, asking people to "focus your prayers" on his 22-year-old passenger, John Graziano, who remains hospitalized
In a post on his MySpace page
, the 17-year-old son of Hulk Hogan said: "I want to thank everyone who has sent their support to me. Right now I would like to ask all of you to focus your prayers on my friend John."
His 19-year-old sister Brooke Hogan echoed the sentiments on her own MySpace page,
adding: "You have all been so wonderful to reach out to me and my family during this time. As you may know, Nick has been released from the hospital, but our good friend John remains hospitalized. Please send your love and prayers to John and his family."
Nick (real name: Nick Bollea) was released from St. Petersburg's Bayfront Medical Center after Sunday's crash, in which the VH1 reality star's Toyota Supra careened off the road, striking a 25-ft.-tall palm tree. No charges have been filed, but police say the case remains under investigation, and Hogan was traveling at an "excessive speed" at the time of the crash.
Graziano, a Marine just back from Iraq, was listed in critical condition. His grandmother Catherine told the Tampa Tribune
the prognosis didn't look good.
"To come home from Iraq and for this to happen," she said.
