Tar Heels' Kendall Marshall ruled out

ST. LOUIS -- North Carolina point guard Kendall Marshall will not play or be in uniform against Kansas in the NCAA Midwest Region final Sunday, the school confirmed about 90 minutes before tipoff.

Marshall, who fractured his right wrist last Sunday and had a screw inserted Monday, went through non-contact practice for the first time Saturday. But he said after that practice that a determination would not be made until after shootaround on Sunday.

"Nothing hurts more than not being able to physically help your team, but I'm here with them spiritually now more than ever," said a Sunday afternoon post on Marshall's Twitter account.

He said a committee of five -- himself, his parents, athletic trainer Chris Hirth and coach Roy Williams -- would be involved in the decision. The most important factors, Williams said Saturday, would be Marshall's pain, and how effective he could be for the team.

The news is a huge blow for the top-seeded Tar Heels, whose offense was out of sync when Marshall was sidelined against 13th-seeded Ohio on Friday. UNC committed a season-high 24 turnovers in that game, and needed overtime to advance.

Marshall, a sophomore Cousy Award finalist, averaged 8.1 points and 9.8 assists this season. Freshman Stilman White will start his second straight game in his absence.
