The wife of Broncos star Emmanuel Sanders is pulling the plug on their brief marriage, despite the fact she's about to give birth to their 2nd child any day ... TMZ Sports has learned.
Gabriella Sanders -- who is due this month -- filed divorce docs in Texas at the end of October, a few days before the couple's 3 year wedding anniversary.
According to the court docs, GS says "the marriage has become insupportable because of discord or conflict of personalities," but doesn't say exactly what caused the split.
