Liverpool owner John Henry has been discharged from hospital after suffering an injury on his yacht, it is understood.
WBZ NewsRadio 1030 said that the tycoon, who also owns the Boston Red Sox, left his private boat in a neck brace after a minor incident on Friday.
Reports suggest the 52-year-old was treated by paramedics at the scene before being put on a stretcher and transported to Massachusetts General Hospital by ambulance.
Massachusetts General Hospital confirmed Henry had been admitted to their emergency room on Friday night, and he is understood to have now been discharged.
Reports of the incident surfaced less than 24 hours before Liverpool's Merseyside derby clash with Everton at Goodison Park, and on the day the Red Sox parted company with double World Series-winning manager Terry Francona.
The Illinois-born businessman bought the Florida Marlins for a reported USD158million in 1999, selling the club three years later.
He then headed up the establishment of New England Sports Ventures (NESV), which purchased the Boston Red Sox for USD700million later the same year.
He made his move into English football last October, when Liverpool accepted a bid - believed to be £300million - from NESV.
After bringing in club legend Kenny Dalglish to replace Roy Hodgson as manager at the start of 2011, NESV supplied a transfer kitty for the Reds to strengthen their squad with big-money signings which included strike duo Luis Suarez and Andy Carroll in January and Stewart Downing, Jordan Henderson, Jose Enrique and Charlie Adam over the summer.
