job asked for references monday, haven’t heard from them since

title. i had a third and final interview last thursday that went well. they told me they had a couple of interviews for friday that they would get back to me by monday at noon. sure enough, around 10am on monday, they call me and tell me they want to move forward with next steps but before they can provide a job offer they need to check references. i give them my references, and it’s been silence since. correspondence with them has been quick up until now. after my second interview, the hiring manager told me the recruiter reaches out to everyone regardless if they were moving forward or not, which is also adding to my confusion. 2/3 of my references say they’ve spoken with them already, and my third says she hasn’t heard anything from them. should i reach out for an update?
