The 6-foot-11, 235-pound Petrusev is the leading scorer and rebounder for the top-ranked Bulldogs (16-1), averaging 16.6 points and 8.1 rebounds per game for a team that has won eight in a row heading into Thursday's matchup with San Diego.
Also featured in Wednesday's update was Dayton's Obi Toppin, who has helped the Flyers emerge as part of the national picture. The 6-foot-9, 220-pound Toppin ranks second in the Atlantic 10 with 19.5 points per game, and also leads No. 15 Dayton in rebounds with 7.7 per outing.
Toppin was ranked No. 13 in ESPN's most recent NBA mock draft.
Notables dropped from the watch list since the 50-player preseason announcement included injured North Carolina guard Cole Anthony and former Memphis center James Wiseman, who announced his departure from the program last month.
