A Stanley Cup Final reporter looked more athletic than a lot of the Florida Panthers did on Monday night ... using some quick-thinking reflexes to keep an obnoxious fan out of her live shot.
The wild moment all went down toward the end of the Golden Knights' 7--2 blowout win over the Panthers in Las Vegas ... when Samantha Rivera was trying to recap Florida's loss on camera.
As the CBS Miami reporter was setting the scene at T-Mobile Arena for her viewers ... a fan tried to photobomb her shot -- and Rivera was having absolutely none of it.
You can see in a replay of her on-cam appearance, Rivera had to use a massive stiff arm to push the Knights supporter away from her shot. All the while, she repeated "Nope!" over and over again.
Eventually, the fan got the hint and bolted ... and Rivera finished her segment like a pro. Afterward, she took to Twitter to blast the guy for trying to interrupt her at work.
"Listen," she wrote, "I don't give a damn what team you're rooting for -- get the hell out of my face when I'm working and respect that I'm here to do my job."
Waiting for your permission to load the Instagram Media.
"Excited to get back home to some classy #Panthers fans for game 3!!" she added.
Fans all over social media lauded Rivera's actions ... with many comparing her right arm to none other than NFL star Derrick Henry's!!
No word yet if the Knights are working to identify and potentially punish the fan further ... though if anyone gets any ideas of repeating his act at Game 3 in Sunrise, FL. on Thursday night -- beware!!!
