Former NRL player Alex McKinnon has married his long-term partner Teigan Power in the NSW Hunter Valley.

Ms Power revealed the wedding date to her Instagram followers on Saturday night alongside a photo of the couple, confirming they would tie the knot on Sunday.

"Tomorrow is the day we say 'I do' to the rest of our lives," she wrote. McKinnon shared the same photo of the couple with the message "not long now".

The two were married in front of family and friends after McKinnon fulfilled his promise to rise from his wheelchair on their wedding day.
