Dallas Cowboys kicker Brandon Aubrey is issuing a "my bad" after nailing a cheerleader with his kick on Sunday ... writing a personal note to the woman and wishing her well following the mishap.
Michelle Siemienowski shared the apology on her Instagram ... one day after she was hit in the head during Aubrey's kickoff in the Cowboys' Week 18 matchup against the Washington Commanders.
The incident went viral, and Aubrey -- a pro soccer player before signing with Dallas in 2023 -- did his best to state the obvious and let Siemienowski it was an accident.
