Though Lake Braddock had its way in a 56-31 win against Chantilly to open the Virginia 6A North region playoffs on Friday, the victory came at a price.

Two defensive starters, Dwight Lomax and Lance Hammond, went down with potential season-ending injuries during the game, adding more players to an injury report that was already a bit longer than the No. 3 Bruins would like.

Lomax sustained a fractured kidney after taking a hit on a Chantilly kick return. After laboring through the next several plays, the senior defensive lineman went to the sideline with an intense pain in his side. Lomax was eventually taken to the hospital for precautionary measures and doctors discovered the kidney injury, effectively ending his season. Bruins Coach Jim Poythress said that while Lomax remained hospitalized as of Sunday, his condition is improving and he is awaiting word on if surgery is necessary.

“You feel for the kid because you hate to see his high school career end like that with a very serious injury,” Poythress said. “We’ll miss him on the field, but him making a full recovery is the most important thing.”

Five plays later, Hammond went down with a knee injury. Poythress said an X-ray showed no ligament damage and a MRI is being scheduled, but it is doubtful the senior defensive lineman will play in Friday’s region quarterfinal game against Yorktown.

With two of their starting defensive linemen likely out, the task of slowing down Yorktown All-Met running back M.J. Stewart — who missed the Patriots’ first-round win against Fairfax with an ankle injury — could be a bit tougher. But thanks to a system that regulary shuffles players on the offensive and defensive lines, the Bruins have built depth throughout the season.

“We’re hoping that bodes well for us going forward,” Poythress said. “You just have to take the next-man-up mentality.”

Offensively, the Bruins have been without running back Trevor O’Brien, who is considered day-to-day after spraining the medial collateral ligament in his knee during a win against South County on Nov. 1. What’s more, quarterback Caleb Henderson sprained his ankle while attempting to slide in that same South County game.

Henderson showed improvements in his health by rushing for a 38-yard touchdown in Friday’s win, and Dejoun Lee has filled in well for O’Brien, amassing 374 yards and five scores during the last two weeks.
