DURHAM, North Carolina (Ticker) -- The combination of Nik Caner-Medley and Ekene Ibekwe knocked Duke from the ranks of the unbeaten.
Caner-Medley scored 25 points and Ibekwe had six points in the last 82 seconds as Maryland knocked off No. 2 Duke, 75-66, in an Atlantic Coast Conference battle.
The loss leaves just top-ranked Illinois and No. 8 Boston College as the only unbeaten teams in Division I. The Eagles prevailed earlier in the evening, holding off Providence, 78-75.
Caner-Medley, whose averaged over 26 points on 60 percent shooting in his last four games, kept the Terrapins in the game all night with his scoring, five rebounds and four steals. But he left the game with 1:43 to play and Maryland holding a 64-62 lead when he injured his ankle blocking a shot by Duke's J.J. Redick.
"He's (Medley) really started to change his game to where he does more things on the court," Maryland coach Gary Williams said. "I think that he's been kind of a guy who waits for the ball to come to him as a shooter his first two years and this year he started to be more aggressive with the ball.
"He worked hard this summer with his ball handling and he's in better control now when he drives now. Last year, he would charge every time he took it to the lane, and this year he's doing a pretty good job of that. Plus, he's big, he's 6'7", about 235, he's a big person."
The Blue Devils tied it on a follow shot by Shavlik Randolph before Ibekwe took over. He scored the go-ahead basket in the lane for a 66-64 lead with 92 seconds left and hit four of the Terrapins' eight straight free throws that sealed the victory.
With Duke leading, 40-32, with 17:58 left, Caner-Medley scored nine straight points in less than two minutes to cut the deficit to 45-41. He scored 15 points after intermission.
"He's playing great," Duke coach Mike Krzyzewski said. "He's playing like one of the top players in the league right now. He made really winning plays. He kind of took the game over in that time when the game was kind of decided. It was a short period, but it was such a critical period."
As well as Caner-Medley played, this game was won by Maryland's defense. It held Duke to 33 percent (24-of-72) shooting and 15 points below its average. The Blue Devils came into the game shooting a conference-best 51 percent.
"I thought that we should be a good defensive team this year, and we haven't been all the time, but tonight we were. We really did what we tried to do, and a lot of times that's defense, just carrying out what you're trying to do." Maryland's effort came on the heels of Sunday's 85-69 home loss to North Carolina State.
"After the NC State game, without me saying much, I think the players took it upon themselves to come in here and give a great effort," Williams said. "You can't come in here thinking that you're going to win or anything like that, but we knew that we could give a great effort. And that's what we did, and we played with a lot of confidence down the stretch when it was really tough."
Ibekwe had 15 points and nine rebounds in 22 minutes off the bench and John Gilchrist added 10 for Maryland (12-5, 3-3 ACC), which won a conference road game for the first time this season and snapped a three-game losing streak at Cameron Indoor Stadium.
J.J. Redick scored 20 points but missed 14-of-21 shots for Duke (15-1, 5-1), which was attempting to match the 1985-86 squad for the second-best start in school history. Shelden Williams added 18, 14 rebounds and seven blocks for the Blue Devils.
