Jax was there to apologize but she ended up challenging Buck to a match. Jax refused to apologize and she berated Buck so he announced that Jax would be indefinitely suspended without pay. Jax didn't take kindly to that so she attacked him.
It looks like WWE may be setting up for a woman vs. man match. That was planned at one point in 2019 when they booked Jax vs. Dean Ambrose but those plans in 2019 were scrapped.
The Jax-Pat Buck angle also appears to be another out-of-the-box idea to boost ratings.
