French journalist Jean-Louis Moncet recanted his comments suggesting that Formula 1 legend Michael Schumacher's injuries in a skiing accident last year may have been caused by a wearable camera made by GoPro Inc.
"Talking about GoPro, there were no news. It was just my opinion," Moncet tweeted on Tuesday.
Moncet was reported to have spoken to Schumacher's son, Mick, but the journalist denied this in a tweet earlier this week.
"The problem for Michael was not the hit, but the mounting of the GoPro camera that he had on his helmet that injured his brain," Moncet had told radio station Europe 1 over the weekend.
Up to Wednesday's close, GoPro shares had fallen 14 percent to $72.87 since Moncet's comments.
"His public tweets clearly show that he kind of took his time to correct the record which was harmful and the company is considering several options including the possibility of civil action against the reporter in France," a source inside GoPro told Reuters.
Schumacher, a seven-time Formula 1 champion, suffered severe head injuries in a skiing accident in Meribel in the French Alps on December 29. Schumacher emerged from a medically induced coma in June. He has been receiving treatment at home since September.
