ATLANTA -- North Carolina fans cheered when John Henson re-emerged from the locker room and louder when he re-entered the game in the first half with his left wrist taped.
But Henson had to exit again about a minute later and that wasn't a good omen for the No. 4-ranked Tar Heels as they try to win the ACC Tournament title and lock up a No. 1 seed for the NCAA.
"He couldn't grip the ball or catch it," North Carolina coach Ray Williams said of his All-ACC power forward.
The Tar Heels (28-4) didn't need Henson in its 85-69 quarterfinal victory over Maryland on Friday at Philips Arena. But you don't want to be without your leading rebound, top shot-blocker and third-leading scorer for long.
The 6-foot-11 junior was fouled hard on a shot attempt five minutes into the game and fell hard to the floor with his left wrist bent back under him.
"I tried, but there was no way I could play," Henson said. "I felt a lot better after they did the X-ray [at halftime] and it was just a sprain."
Henson, who came into the ACC Tournament averaging 14.2 points and 10.3 rebounds, spent most of the second half with ice on his wrist after getting three points and four rebounds in seven minutes.
Will Henson be able to play today when the No. 1-seeded Tar Heels play No. 5 seed North Carolina State at 1 p.m. in the first semifinal game?
"I hurt the wrist before and I played with a split," Henson said. "I want to get back out there as soon as I can."
"He'll ice it (Friday night) and we'll see what the doctors say," Williams said.
Kendall Marshall passed out 12 assists to set an ACC single-season record with 311 and was one of five Tar Heels in double figures against Maryland (17-15).
Freshman reserve James Michael McAdoo, playing 29 minutes with Henson out, had 14 points and a team-best eight rebounds. Harrison Barnes and Reggie Bullock each scored 15 for the Tar Heels, with Tyler Zeller adding 14 points and Marshall 13.
Maryland sophomore Terrell Stoglin, the ACC's leading scorer, had 30 points on 11-for-21 shooting that included 5-for-11 from 3-point range.
It has been an injury-plagued season for the Tar Heels, who lost starting guard Dexter Strickland to knee surgery in early February.
N.C. State 67, Virginia 64
C.J. Leslie had 19 points and 14 rebounds and Lorenzo Brown contributed 15 points and eight assists as No. 5 seed North Carolina State (22-11) held on to defeat No. 4 seed Virginia 67-64 in the second afternoon quarterfinal.
Up by nine points in the second half, the Wolfpack struggled at the foul line in the final minutes. But Brown had two free throws with 7.2 seconds left to put N.C. State up by five points.
Mike Scott had 23 points and 10 rebounds for Virginia (22-9). Joe Harris scored 18 and Akil Mitchell had 10 points to go with 12 rebounds as the Cavaliers lost despite shooting 54 percent.
Both N.C. State and Virginia appear headed to the NCAA Tournament along with North Carolina, Duke and Florida State from the ACC.
The Wolfpack had a 13-0 run early in the first half, but needed a four-point play by Scott Wood with less than a second left to take a 36-33 lead into intermission.
Duke 60, Virginia Tech 56
Austin Rivers scored 17 points, including the clinching 3-point play with 15.1 seconds remaining, as No. 6-ranked Duke (27-5) moved into the today's semifinals with a 60-56 victory over Virginia Tech in the first game of the evening session.
The No. 10 Hokies (15-17) had cut a deficit that had been as much as 10 down to 55-51 with 1:08 remain before Rivers, who made the All-ACC first team as a freshman, ran down a long tap-out and scored while being fouled.
Duke won despite shooting just 29.6 percent in the second half and going 5-26 on 3-pointers for the game. Virginia Tech shot 28.1 percent in the first half and 30.2 percent for the game.
Tyler Thornton scored 13 points and Mason Plumlee had 12 points to go with 10 rebounds for Duke. Erick Green and Robert Brown each had 16 points for Virginia Tech.
The Hokies, who had forced Duke into overtime at Durham late in the regular season, overcame an early 13-5 deficit, but the Blue Devils regained control late in the first half and led 31-26 at intermission. Rivers had 11 first-half points.
A 10-2 run in the second half put No. 2 seed Duke up 43-33 and the Blue Devils twice more led by 10 points before the Hokies staged their late rally.
