Gaming regulators plan to hold a pair of virtual hearings next week to decide if they should slap penalties on MGM Springfield and Encore Boston Harbor for a series of illegal sports wagers, according to meeting agendas posted online.

Within the first month of in-person betting, all three casinos in the state reported that patrons were able to place illegal wagers on in-state collegiate sporting events. Members of the Massachusetts Gaming Commission launched investigations and planned judicial-like hearings to determine potential fines and repercussions.

More than $1,200 in wagers were placed on a pair of Harvard University basketball games at MGM Springfield in February because the university was incorrectly listed as an out-of-state institution, Gaming Commission investigators said.
