Loudoun County and Loudoun Valley will face off for the 53rd time on Friday in Leesburg, and the third straight season. It’s a welcome return after a four-year hiatus from 2006-11 when the Vikings competed in the Virginia AAA Cedar Run District.

Loudoun County (5-3, 3-1 Dulles District) quarterback Tae Crews-Naylor will be under center for the Raiders. The dual threat junior missed the Raiders’ Oct. 18 win against Woodgrove due an injury, but returned to lead County to last week’s 17-0 win over Champe.

Senior pocket passer Chad Carrera was the starter in the Woodgrove win. He completed 57 percent of his passes and threw for 325 yards in a come-from-behind 31-28 win.

Loudoun County has won the last two meetings between the rivals by a combined score of 74-26.

The Vikings (7-1, 4-0) haven’t faced an opponent with a winning record since losing to Tuscarora, 34-12, on Sept. 12. Loudoun Valley has run off six wins in a row since.

“We just try to play up to our standards that we’ve set every week,” Loudoun Valley Coach Danny McGrath said. “Our guys have done a great job all year long. It’s a different team every week, and we would like to take a big step forward.”

Loudon’s Valley’s offense is led by junior running back Andrew Cordani, who rushed for just over 1,000 yards last season.

“He carries the ball very well,” McGrath said of Cordani. “I don’t want to jinx him here, but he takes care of the football and has great vision. When he makes a move, it’s hard to stop him.”

McGrath will rely heavily on a Vikings defense that has allowed just over 10 points per game and posted three shutouts.
