Roswell RB Sheldon Evans (1,334 yards rushing for the season) was limited by an ankle injury and rushed for a season-low 23 yards on seven carries in a 29-12 victory over Peachtree Ridge last week, but QB Malik Willis passed for a season-best 292 yards.

Grayson at Colquitt County

When, where: 7:30 p.m. Friday, Mack Tharpe Memorial Stadium, Moultrie

Records, rankings: Grayson is 11-1, the No. 1 seed from Region 8-AAAAAAA and No. 1; Colquitt County is 8-4, the No. 1 seed from 1-AAAAAAA and No. 6.

Last meeting: Colquitt County won 21-6 in 2013.

Things to know: Grayson and Colquitt County have been perhaps the top two programs in the highest classification over the past decade, winning a combined three state titles (Grayson in 2011, Colquitt County in 2014 and 2015). Grayson has had nine 10-win seasons and seven quarterfinal appearances since 2007, and Colquitt County has reached the semifinals in the highest class a state-record seven consecutive times. The quarterback battle will be worth watching. Colquitt's Jay Saunders passed for a season-high 357 yards in a 66-35 win over Brookwood last week and has 2,615 yards and 22 TDs for the season. Grayson's Chase Brice threw for 316 yards and five TDs in a 59-21 win over Woodstock, giving him 2,324 yards and 25 TDs on 212 attempts.

Winner plays: Mill Creek/McEachern winner

Mill Creek at McEachern

When, where: 7:30 p.m. Friday, Walter H. Cantrell Stadium, Powder Springs

Records, rankings: Mill Creek is 12-0, the No. 1 seed from Region 6-AAAAAAA and No. 3; McEachern is 11-1, the No. 1 seed from 3-AAAAAAA and No. 4.

Last meeting: This is the teams' first meeting.

Things to know: Mill Creek is in the quarterfinals for the second consecutive season and fourth time in school history. McEachern reached the semifinals in 2013 and 2014 before losing in the second round last year. McEachern's running game has emerged as a force late in the season, averaging 266 yards in its past three games. Quay Holmes ran for 201 yards and Paris Brown had 140 in a 47-29 second-round victory over Parkview. This week, however, the Indians face a Mill Creek defense that gives up just 28 yards per game rushing through the first 11 games and allowed 15 total yards in the first half of a 56-21 win over Cherokee last week. Mill Creek gets a little more than half of its offense from a passing game led by Cameron Turley, who has thrown for 2,139 yards.
