Dubose committed to Miami last week, but wavered heading into signing day. Prior to his visit with the Hurricanes, the 6-4, 245-pound sack artist was considered a heavy Louisville lean.
Dubose visited Louisville last month, and gave the Cardinals strong praise after that trip. He provides a significant late boost to Charlie Strong's 2011 recruiting class.
One of the top prospects in Broward County, Dubose is considered one of the Top 5 defensive end prospects in Florida. He could compete for a starting job as a freshman.
As a senior, Dubose was named the Orlando Sun Sentinel's Broward County Defensive Player of the Year after recording 60 tackles, 11 sacks and one interception this past season.
Last year as a junior, Dubose registered 55 tackles, 11 sacks, and three forced fumbles.
There has been considerable speculation about his academic status, but Dubose's coach, Donnell Bennett, believes Dubose can qualify to play next season.
"I think he'll be OK," Bennett said. "He's made a big transition in his life and really grown up in the past year and is working hard to take care of his business."
Bennett said he doesn't think the academic "stuff" will play too big a part in his college decision.
Dubose is the 19th member of Charlie Strong's recruiting class.
