A Morel-Lavallée lesion is a relatively rare condition involving a closed, 
degloving injury to the pelvis, resulting in a blood-filled cystic cavity 
created by separation of the subcutaneous tissue from the underlying fascia. 
This injury typically occurs following high-speed trauma. We describe a case 
that occurred in a professional American football player who was treated with 
percutaneous decompression and evacuation of the hematoma. The player returned 
to playing football at the professional level 22 days after the injury without 
residual deformity or disability.
