Bill Belichick and Jordon Hudson have been fueling engagement speculation for weeks ... and, Jordon's jewelry won't shut down the rumors -- 'cause it looks like she's wearing a ring on that finger.

It's hard to make out if this is a big diamond engagement ring or not -- and, jewelry can just be jewelry without a bigger meaning sometimes -- but, with all the rumors swirling around the couple right now, it will certainly perk up eyebrows.
