The defense escalated its campaign to impeach Detective Fuhrman's credibility by seeking approval for three additional witnesses while expert testimony from Professor MacDonell directly challenged the prosecution's interpretation of blood evidence on the socks. The court ordered a hearing on a controversial pre-trial DNA news leak that suggested potential evidence tampering at the lab. The day ended prematurely due to a juror medical emergency.

• Judge Ito deferred ruling on three additional witnesses to impeach Detective Fuhrman by proving he lied about never using racial slurs.
• Professor MacDonell testified the bloody sock stain was a compression transfer with evidence of blood soaking through, contradicting prosecution expert Gary Sims.
• Court ordered reporter Tracie Savage to testify about a September 1995 KNBC news leak claiming DNA results on socks—before any DNA testing had occurred.
• Judge Ito restricted the prosecution's ability to present Thano Peratis impeachment evidence to the rebuttal phase only.
• Court adjourned early due to a juror medical emergency.
