Three Duke football players were dismissed from the program yesterday by Coach Ted Roof and a fourth, starting quarterback Zack Asack, was suspended and will miss the 2006 season because of a serious academic infraction.

The players dismissed were Andreas Platt, Deon Adams and Joe Suder. Platt, a 6-2, 200-pound strong safety, is from Greensboro and played at Jamestown's Ragsdale High School, and Adams, a 6-1, 195-pound receiver, is also from Greensboro, where he played at Smith High School.

Platt would have been a third-year sophomore after being redshirted in 2004 as a freshman. Adams would have been a senior. Suder is a 6-6, 340-pound defensive tackle from Reno, Nev., who redshirted last season as a freshman.

Duke athletics officials said that the three players were dismissed for violating team regulations. Platt, reached at home last night, wouldn't say what led to his dismissal. A DWI charge at least contributed to the situation.

Platt was found guilty of the charge in January in Orange County District Court for a July 16, 2005, minor traffic accident in Chapel Hill.

"I ain't got nothing to say," Platt said. "I ain't worried about nothing. It was just a mutual agreement that it was time for a change. I'm going to another school."

Platt said that he plans to continue his education and football career at Western Carolina.

Platt played in 11 games at Duke and had 15 tackles. Adams played in 27 games and caught 12 passes for 125 yards.

Asack was suspended for plagiarism and will not be able to attended classes in the coming academic year. School officials said that he will be eligible to return to school and to the football program in the summer of 2007.

"I made a mistake and am remorseful," Asack said in a prepared statement released by Duke. "I take full responsibility for my actions. I wish the team well and look forward to returning next summer. I love it here at Duke."

Asack would have been a sophomore this season. He started six of the Blue Devils' final seven games last season and finished the season with 966 passing yards. He completed 50 percent of his passes and had five touchdown passes. He was intercepted eight times.

Asack's absence will likely thrust rising sophomore Marcus Jones into the starting quarterback role. The only other recruited quarterback in the Duke program next season is incoming freshman Thaddeus Lewis.

Roof said that the Blue Devils will move forward and try to offset Asack's absence in the coming season.

"Sometimes great young men make poor decisions and that is the case in this situation," Roof said in a prepared statement.

"While I certainly don't condone his actions, I have been impressed with the manner in which Zack has handled this issue.

"I fully support Zack and am confident that he will grow in many areas as a result of this situation.

"When you are part of a family and make an uncharacteristic mistake, you are not kicked out of the family. Zack will remain part of the Duke football family and will be supported by everyone in our program."
