The B1G has confirmed the criteria that will be used to determine a regular-season champion in the conference.

According to Noah Trister with the Associated Press, the B1G will use winning percentage to determine a conference champion. That point of clarification was needed as Michigan is currently on track to play 17 conference games instead of the regularly scheduled 20 due to their long pause related to COVID-19.

The clarification comes ahead of Tuesday’s top-five matchup between No. 2 Michigan and No. 4 Illinois. It also confirms a win for the Wolverines on Tuesday would award Juwan Howard’s squad the regular-season conference championship.

Currently with a record of 13-1, Michigan now needs just one win in its final three games to secure the championship. The Wolverines play at home vs Illinois, vs Michigan State in Ann Arbor, and finish against Michigan State in East Lansing.

Should Illinois pull off the upset Tuesday, a challenge made even bigger due to the absence of Ayo Dosunmu, the Illini would maintain a slim shot to capture the regular-season title. Illinois must first win its last two games to finish at 16-4 (.800 winning percentage) to have a chance. The Illini would then need Michigan State to sweep the Wolverines, dropping Michigan to 13-4 (.764 winning percentage).

Can Michigan lock down the championship, or will Illinois prolong the battle? Tuesday’s tipoff is set for 7 pm EST on ESPN.
