Jordan asserts the father of Pamela Smith's teenage son, Grant, already has been identified, TMZ reported.
Smith alleges Grant was conceived during a 1995 tryst with Jordan.
"Public records show that the paternity of the child was established in a prior case in this same court many years ago and that Michael Jordan is not the father," Jordan's representative said.
"It is unfortunate that well-known figures are the target of these kind of claims. Michael Jordan will vigorously defend himself and his reputation."
