MMAJunkie.com has the story:
Although former UFC welterweight champion Matt Hughes (43-7 MMA, 16-5 UFC) was expected to make his promotional return in February, possibly at UFC 109 or UFC 110, the veteran fighter now says he's likely to return on April 10.
Currently, the UFC has not officially announced any events for the date, though it presumably would be UFC 112.
Hughes hasn't fought since his decision victory over Matt Serra at UFC 98 in July.
“I'll tell you later who and where (I fight) when I find out for sure if it is confirmed,” Hughes recently wrote on his official Web site, matt-hughes.com.
