Sarah Kaufman out of UFN 28, no opponent.

Sarah Kaufman vs. Sara McMann, was canceled when McMann withdrew for undisclosed reasons.  Now it looks like Sarah Kaufman wont fight on UFC Fight Night 28 either. But this time because they were unable to find her an opponent.

Well, it's official: no replacement opponent would take the fight so I'm off #UFN27. I'm devastated about pushing my @ufc debut back.
