There have been a ton of rumors surrounding Puka Nacua's dating life recently, but it appears we can cross at least one woman off his list -- fitness influencer Sara Saffari.

The latest speculation spread on Monday ... with accounts pointing out how the L.A. Rams superstar and content creator were spotted together a handful of times ... and at least one instance seemed romantic, as the two held hands at LAX.

They also made cameos in a YouTube video posted on Nick Nayersina's channel ... when their group of friends called them a great duo while at Topgolf.

All that being said, Saffari was quick to shut down the talk ... going to Instagram comments to set the record straight.

"We're siblings chill," Saffari claimed.

Unclear if she's just trying to put out a fire to keep things lowkey or if their recent hangs really were simply platonic ... but we'll go ahead and assume it's a real denial.

It's been an eventful offseason for Nacua -- he's enjoying his time off the gridiron with numerous beautiful ladies after splitting from his girlfriend, Hallie Aiono ... but if Saffari's telling the truth, it doesn't mean everyone he's out in public with is his next partner.
