Maryland men's lacrosse defenseman Bryce Young is week-to-week after suffering an undisclosed injury, coach John Tillman said after Saturday's 10-4 win against Navy.

Attackman Steven Shollenberger will be also sidelined for the remainder of the season because of an injury, Tillman said.

Young was expected to anchor Maryland's defense in his senior year after Tim Muller and Isaiah Davis-Allen graduated last season. He started every game in 2017, scoring two goals while securing 38 ground balls and forcing 13 turnovers.

Young participated in the team's scrimmage against Virginia last weekend and practiced this week, Tillman said. Then, the team trainer called Tillman on Friday and said that Young couldn't play. Tillman declined to identify the injury.

"I feel very comfortable he will be back," Tillman said. "We make sure we have our bases covered. We have a 'next man' mentality. The kids really bought into that."

Shollenberger will miss all of 2018. The Damascus native played in nine games as a freshman last season. Inside Lacrosse ranked him the No. 62 player in the 2016 recruiting class.
