LAS VEGAS (AP) — Notre Dame star guard Markus Burton is expected to miss several weeks with a season-ending knee injury, sources told ESPN on Wednesday.

Burton suffered the injury Tuesday night against Rutgers while playing just three minutes before exiting the game.

Burton, a 5-foot-11 point guard, was one of the top freshmen in the country last season and was named to the preseason All-ACC team last month. He entered this week averaging 21.4 points and 5.2 assists and scored 29 points against North Dakota and 25 points against Elon in the two games before the Players Era Festival in Las Vegas.

Notre Dame suffered its second straight loss on Tuesday when it fell to overtime without Burton. The Fighting Irish face No. 6 Houston on Wednesday night and round out their time in Vegas on Saturday against a yet-to-be-determined opponent before traveling to Georgia next week.

Sophomore Logan Imes saw a huge increase in playing time with Burton out, going from a total of five minutes in his last three games to 35 minutes against Rutgers. He scored eight points and hit two 3-pointers before being fouled. Imes and senior Julian Roper II will be forced to take on more responsibility on the perimeter in Burton’s absence.
