What happened: Vieira lost a unanimous decision to Cris Cyborg in Tampa in August after missing weight by seven pounds. Vieira said she took medication for a long-term knee injury after leaving the UFC testing pool and stopped it after signing with PFL. The suspension is retroactive to the fight date.

Why it matters: The case stalls her PFL start after a May UFC exit following 10 years without a testing incident. It removes a new challenger from the featherweight mix during Cyborg's title reign. PFL now faces a credibility test on enforcement as it builds around veteran additions.

What to watch: Vieira said she will focus on knee maintenance while training for a return. Her next PFL booking will define her standing in the division.
