Xavier will have to play out the rest of the season without the services of star point guard Edmond Sumner, who unfortunately tore his ACL in his left knee during the second half of the Muskateers' win over St. John's on Sunday.

Sumner was enjoying a breakout redshirt sophomore season, flashing improved numbers across the board. The 6-foot-6 Detroit native was averaging 15.0 points, 5.0 assists, 4.3 rebounds and 1.3 steals per game. His 47.9 percent field-goal rate is a whopping 8.2 percentage point climb over his 2015-16 line.

Xavier coach Chris Mack shared a statement through the team's Twitter account, calling his guard "an awesome kid, a fearless competitor and a terrific teammate."

The Muskateers, who fell out of the latest AP Top 25 after dropping four of their last six games following a 13-2 start, will now have their work cut out for them to keep their tournament résumé strong. Sumner ranks second on the team in points, first in blocks and assists — in fact, he has been credited with a third of the team's assists this season — and he is third in rebounds. Mack will likely turn to true freshman Quentin Goodin to pick up the duties at point.
