WINSTON-SALEM, N.C. (AP) — Mike Krzyzewski may have poured too much emotion into No. 4 Duke’s trip to Wake Forest.

The rest of the Blue Devils didn’t seem to have enough.

The Demon Deacons upset Duke 82-72 on Wednesday night after Coach K experienced enough dizziness and light-headedness to force him to kneel during a late timeout and skip his postgame news conference.

Associate head coach Steve Wojciechowski — who filled in for him — says Krzyzewski has not been sick, is in good shape and expects to make a full recovery.

“There was a great emotional investment in the game,” Wojciechowski said, “and I think maybe the emotion got the better of him.”

The rest of the team might not have had that problem.

Duke (23-7, 12-5 Atlantic Coast Conference) was playing for the first time in over a week — after going 4-1 in an 11-day span before that — and Wojciechowski says the Blue Devils simply weren’t prepared emotionally.

After taking a late seven-point lead, Duke went without a field goal for 5 critical minutes while allowing the Demon Deacons (16-14, 6-11) to reel off 17 straight points and go up by double figures.

“I’m not sure that ... we were as prepared from an emotional standpoint,” Wojciechowski said. “I don’t know if our guys had the needed edge to compete against a Wake Forest team that played their hearts out.”

Tyler Cavanaugh scored a career-high 20 points, Travis McKie added 19 in his final scheduled home game and Codi Miller-McIntyre had 13 for the Demon Deacons.

They followed one of their worst performances of the season — a home loss to sub-.500 Boston College — with one of their best. Their first win over Duke since 2009 also marked their biggest upset since they knocked off No. 2 Miami last February.

“I couldn’t picture a better ending,” McKie said. “Everything was just perfect tonight. The fans were perfect. Me, being my last (home) game, everything we did was great.”

Jabari Parker scored 19 points and Rodney Hood added 16 for the Blue Devils, who missed six straight shots down the stretch and were just 6 of 27 from 3-point range while falling to 4-5 in ACC road games.

Parker’s dunk with just under 6 minutes left gave the Blue Devils their largest lead, 66-59, and by then, they appeared on their way to their ninth straight win in the series.
