"Making a turn-I take the turn too sharply", Massaquoi says, reliving the horrifying moment.
The 31-year-old Massaquoi, who was a second-round selection by the Browns in the 2009 NFL Draft out of the University of Georgia, said that he had to have four fingers on his hand amputated over time once the doctors deemed them unsavable.
Now, Massaquoi has lost one of those hands.
Massaquoi recent shared his story of losing the majority of his left hand on The Players' Tribune in an ATV accident.
He had just endured an ATV accident during an outing with his friends and heard what he described as an "explosion" in his hand.
With only his thumb left, Massaquoi now wears a prosthetic hand after what was supposed to be a fun afternoon turned tragic.
Massaquoi detailed this experience in an interview he recorded for The Players' Tribune. However, as the weeks passed, it was clear his fingers weren't responding and four of them had to be removed.
Massaquoi believed he had only broken his hand, but several of his friends thought his hand looked as if it went through a meat grinder because of how badly it looked. "This finger's not going to make it, we have to take it off, '" Massaquoi said. "It gives you a perspective of how precious life is".
"I went with denial, I went through fear of what was going to come", Massaquoi said. He also explains the mental adjustment he had to make once he realized a part of what made him who he was will no longer be there. "Sometimes you see yourself as different, and they still see you as you".
Able to feel and move his thumb, Massaquoi said, "I'm just grateful that I still have it". I want to thank my wife for being my rock throughout this whole process, and I want to thank my family and friends for their support.
"Real friends, real relationships mean the world to me, " he said. He caught a total of 118 passes for 1,745 yards and 7 touchdowns in that span before being signed and released by the Jacksonville Jaguars and New York Jets in 2013.
