U.S. District Judge Charles R. Simpson III on Thursday granted Karen Sypher more time to ask for a new trial.
Sypher was convicted August 5 of threatening communications with intent to extort, making a false statement to a government agent and retaliating against a victim.
The charges were linked to a sexual encounter Sypher had with University of Louisville men's basketball coach Rick Pitino.
Federal rules already allow for a motion for a new trial to be filed within three years of conviction if there is newly discovered evidence. If there is any other reason for a new trial, a motion must be filed within 14 days of a conviction.

Last month, Sypher's attorney James Earhart asked for an extension of the two-week timeframe, saying he was investigating whether a prosecution witness or witnesses committed perjury during the trial. He said at the time that he wasn't sure whether the circumstances involved newly discovered evidence.
On Thursday, Earhart declined to name any witness who was involved in his investigation.
In the judges' order on Thursday, he gave Sypher 45 days from her conviction date in which to file a motion for a new trial.
Earhart said Thursday in an interview he had not yet decided whether to ask for a new trial.
