Conor McGregor's now-infamous dolly toss in the lead-up to UFC 223 did not endear him to UFC strawweight champion Rose Namajunas.

McGregor, of course, went on a rampage backstage at the Barclays Center in Brooklyn as he sought out Khabib Nurmagomedov. The former featherweight and lightweight champion hurled a dolly at the bus, which Namajunas was on, along with other UFC 223 fighters, and broke one of the windows, injuring several fighters.

Bleacher Report reached out to Namajunas' longtime partner, Pat Barry, to confirm Issac Feldman's Twitter report. Barry confirmed that McGregor did direct-message the champion on Instagram to offer his apologies in the wake of his shenanigans. Her response? A simple "F--k that, call Pat!"

In the wake of the fracas, UFC President Dana White told reporters that she was very upset and walked back to her hotel (h/t Newsday's Ryan Gerbosi). It would be an understandable response from Namajunas, who was laser-focused on her title defense against Joanna Jedrzejczyk in the midst of the madness.

Namajunas has been outspoken since winning the title on how champions should present themselves. After winning the belt at UFC 217, Namajunas said: "I'm sick of all the hate and anger. I feel like we have a duty as fighters to try and be a better example, you know" (h/t MMAJunkie.com's Steve Marrocco and Ken Hathaway).

McGregor's wild antics nearly cost Namajunas, and the 115-pound queen did not hesitate to express herself forcefully to the worldwide superstar. Namajunas would go on to win a hard-fought decision against Jedrzejczyk.
