The script has flipped for Georgetown. After a 12-2 start, with wins in their first three Big East games, the Hoyas have lost four straight and are saddled with injury concerns.Their top scorer and rebounder, Thomas Sorber, has a sore elbow and their best long-range threat, Jayden Epps, has been hobbled by ankle and hamstring issues.It’s a lot for Georgetown (12-6, 3-4 Big East) to overcome as it prepares for a tough test Monday evening at Villanova (12-7, 5-3).The Hoyas are reeling after falling Friday at home to lowly DePaul, 73-68. The win snapped the Blue Demons’ 39-game regular-season conference losing streak.Without Sorber and Epps in the lineup, Georgetown trailed by 17 points in the first half and 16 after intermission.”Our injuries are really catching up to us here,” Hoyas coach Ed Cooley said. “There’s no excuses. We didn’t start playing until the 30-minute mark.”Over the last four weeks, Epps has missed three games and been ineffective in limited minutes in three others.Since Epps was originally hurt, Georgetown has had strong performances, such as a win over Xavier and competitive defeats against then-No. 7 Marquette and then-No. 9 UConn.But compensating for the loss of Epps and Sorber, who averages 14.2 points, 8.6 rebounds and 2.5 blocks per game, was too big an ask for the Hoyas on Friday.
