Linn-Mar and Kennedy boys basketball fans might want to circle Tuesday, March 3 on their calendar.

That's the day their teams might collide in the Class 4A substate finals, with a berth in the state tournament at stake.

The IHSAA announced the groupings for all the postseason tournaments Monday for Class 4A, 3A, 2A and 1A.

Linn-Mar and Kennedy were placed in the same substate with Cedar Falls, Marshalltown, Waterloo East and Waterloo West. The pairings will be announced next month, based on team results in Games 5 through 15.

Linn-Mar, Kennedy and Cedar Falls are the strongest teams in Substate 3 and will be seeded 1-2-3, based on their records after the 15th game. Linn-Mar has already defeated Kennedy (74-61) and Cedar Falls (81-45) and could have the inside track to the No. 1 seed. Kennedy can help itself with a victory at Cedar Falls Friday night.

Washington, Prairie and Jefferson were placed in Class 4A Substate 6 with Iowa City West, which is ranked No. 1 and seeking its fourth straight state title with another potent club.

The Xavier Saints and Marion Indians were placed in the same Class 3A district with Benton Community and Solon. The Saints and Indians could meet in the first round or second round of the district tournament, with a substate game to follow.

Cedar Valley Christian, which is winless this season, was placed in a Class 1A district with Belle Plaine, BGM, English Valleys, HLV, Iowa Mennonite, Iowa Valley, Montezuma and Tri-County.

The Class 1A district tournament starts Feb. 16. The Class 3A district tournament and the Class 4A substate tournament begin Feb. 23. The state tournament is scheduled for March 9-14.
