Jerry Greer, the 19-year-old son of country music star Craig Morgan, has been reported missing.
Sources say Greer was riding an inner tube that was being pulled by a boat on the Tennessee River when what's been described as a "freak accident" occurred.
Details are scarce at this time, but Morgan and his wife, Karen Greer, have confirmed that Jerry's whereabouts are currently unknown.
"The family is grateful for everyone’s support and prayers and requests privacy during this difficult time," reads a statement issued by Morgan's reps this morning.
Authorities have confirmed that two teens were tubing when the unspecified accident took place.
One of them, who has not yet been identified as Greer, never resurfaced.
All parties involved in the accident were reportedly wearing life jackets.
Helicopters and rescue boats have been combing the area since 4 pm Sunday afternoon.
Asked if they expected to find Greer alive, authorities responded that they have not "declared anything other than searching."
Morgan and his wife have four children together, including Greer, who recently graduated from Dickson County High School.
Morgan frequently speaks of his love for his wife and kids in interviews.
"I have a wonderful family," he told FOX411 Country last year.
"My wife is great and supportive, making sure that I'm doing the things I need to be doing at home and that I need to be doing out on the road."
