Accounts connected with a gambling ring that is under federal investigation for its participation in two NBA betting cases have been tied to "unusual wagering activity" on at least three men's college basketball programs this season. The three schools -- North Carolina A&T, Mississippi Valley State and Eastern Michigan -- were all reportedly bet against by the gambling ring and flagged by betting integrity monitors at various points this season, according to ESPN. North Carolina A&T recently suspended three basketball players -- including the top two scorers on the season for "violating team rules" last week -- though it's unclear if the indefinite suspensions are tied to the betting case.
