Avulsion (tearing) of the flexor tendon to the fingertip usually occurs from grabbing a jersey during a tackle. It most often affects the ring finger. Following the injury, the fingertip cannot be flexed (bent down) and the tendon can often be felt in the finger or the palm. X-rays will rule out an associated fracture. Treatment consists of surgery to reattach the tendon to the base of the fingertip.
