No matter how much his thumb hurts -- and it did plenty Saturday -- University of Miami quarterback Jacory Harris made one thing clear against Duke: He's not going to let the pain or his struggles keep him from leading the Canes to victory.

Playing with the thumb and index finger on his throwing hand wrapped in heavy tape, Harris fought off a shaky first half and engineered the sixth come-from-behind win of his career as UM rallied for a 34-16 victory over the Blue Devils at Land Shark Stadium.

The Canes' 21 fourth quarter points weren't all a product of Harris' arm. Damien Berry's tough running and Darryl Sharpton's 73-yard interception were big, too.

But Harris still made plenty of crucial third-down passes to keep drives alive in the second half. He finished 25 for 43 with 348 yards and two touchdowns to put the bad taste of last week's four interceptions behind him.

``I just got a real bad thumb injury,'' said Harris, whose throwing arm was in a sling after the game. ``It's nothing much. As long as my adrenaline is running, I'll be OK.''

For a half, adrenaline didn't seem to be enough. After sitting out practice for most of the week, Harris had trouble gripping the ball and throwing it with much accuracy. He sailed passes over open receivers heads and underthrew them, too.

He was intercepted by Duke's Vincent Rey -- Harris' 17th of the season -- and fumbled inside the Duke 20 in the second quarter.

Sharpton said Harris came over and apologized to UM's defense on the sideline before the Canes went into the half trailing 13-10.

``I couldn't really feel the ball,'' said Harris, who said he asked center A.J. Trump to snap the ball more softly. ``I was throwing side arm. I just wasn't being me. Then, I loosened up and had fun in the second half.''

Harris said he got pumped up when he heard Duke players celebrating at halftime in the stadium tunnel. Linebacker Sean Spence and running back Graig Cooper also gave him pep talks.

But what really got him going, Harris said, was when he connected with tight end Jimmy Graham on a third-and-8 from UM's 12. Graham finished with a career-high five catches for 73 yards.

``I told him no matter where you throw it, I'm going to get it,'' Graham said. ``I think we have good enough wide receivers to make up for anything he does. But he had a great [day]. He battled through the pain and brought us out victorious.''

Hankerson, who had a career-high eight catches for 143 yards, said he also felt the need to help his quarterback out. On his 44-yard touchdown catch in the fourth quarter, Hankerson saved his quarterback by coming back for the underthrown pass and outleaping the defender.

``We know he's not healthy, and we have go out there and make plays,'' he said. ``When the ball is short, we got to go back and get the ball to help out the team. Jacory is a warrior. We have to help him.''

Harris refuses to sit out.

``I have to deliver for this team,'' he said. ``They're behind me and as long as they are behind me and backing me up, I got to keep grinding.''
