How long to wait until I call the HR rep?

Hey all,

I verbally accepted an offer this past Friday at around 3:30pm. They let me know that they'll have an offer sent to me by Monday (today) at the latest.

After the call, the man sent me an email detailing what we had talked about (including sending the offer), my official title, salary, and my tentative start date of a week from today.

It is monday and he hasn't sent it.

When should I reach out to the man who offered me the role on the phone on Friday? It didn't feel like a ghosting, since I got all of the details from him by email about the offer/salary/start date, but you never know.
