Virginia AAA Northern Region Division 5 final

No. 8 Yorktown at No. 2 Stone Bridge

Friday, 1:30 p.m.

At stake: A berth in the AAA Division 5 semifinals.

Watch for: Stone Bridge (12-0) has been impressive on both sides of the ball all season. Defensively, the Bulldogs have held eight of their opponents to a touchdown or less behind defensive linemen Jonathan Allen and Jesse Mizell while quarterback Ryan Burns (2,174 yards, 26 touchdowns) and tailback Sterling Dailey (1,194 yards, 18 touchdowns) lead a high-powered offense. Yorktown (12-0) is fueled by National District Offensive Player of the Year M.J. Stewart, who has racked up 1,640 rushing yards and 23 touchdowns. Stewart has some help in the backfield in the form of fullback Arturo Brown, who had a season-high 156 yards in last week’s win against South County.

The Skinny: This is the first-ever meeting between the schools. Yorktown is looking for redemption after falling in last year’s region final; Stone Bridge is vying to reclaim the region crown it won five times between 2005 and 2010.

Virginia AAA Northern Region Division 6 final

No. 15 Oakton at No. 4 Westfield

Saturday, 1:30 p.m.

At stake: A berth in the AAA Division 6 semifinals.

Watch for: Westfield (12-0) enters its second straight region final behind the surging play of tailback Dalaun Richardson, who has amassed 1,691 yards and 17 touchdowns this season. The Bulldogs have put up 40-plus points in four of their last six games. Westfield beat Oakton, 28-14, in their first meeting this season, but the Cougars (8-4) are on a roll with upset playoff victories against Lake Braddock and Centreville. Cougars quarterback Kyle Downer (2,268 total yards, 32 total touchdowns), propelled Oakton into the final with a touchdown run as time expired that ousted defending region champion Centreville.

The Skinny: Westfield is seeking redemption after losing last year’s title game on a late field goal; Oakton, which lost its final four regular season games and had not won a playoff game since 2008, looks to continue its hot streak.
