Each week the Pittsburgh Union Progress issues its high school football rankings throughout this season, with all rankings voted on by the PUP sports staff.

5. Canon-McMillan (2-6)

The skinny: The top two spots remain unchanged, as Central Catholic cruised to a 59-13 win at Norwin while North Allegheny rolled to a 38-6 triumph at Canon-McMillan. Seneca Valley switched spots with Hempfield after beating the Spartans at home, 27-15, to take over sole possession of third place and all but lock up a playoff spot. Hempfield can go a long way toward clinching the fourth and final playoff berth in Class 6A with a win this week against Mt. Lebanon.

2. Pine-Richland (7-0)

3. Peters Township (7-1)

The skinny: Upper St. Clair used its suffocating defense to earn another marquee victory, knocking off an undefeated conference rival for the third week in a row with a 14-10 win at Bethel Park in the PUP game of the week. The Black Hawks came into the game averaging a WPIAL-leading 51 points per game. Pine-Richland kept pace with the Panthers in the race for the No. 1 seed in Class 5A by shutting out Latrobe, 42-0.

The skinny: The top two teams each took care of business to set up one of the biggest games of the year. Montour will play host Friday to three-time defending WPIAL champion Aliquippa, with the Parkway Conference crown up for grabs, after the Quips won at Blackhawk, 48-13, and the Spartans took home a 47-13 win at Ambridge. Thomas Jefferson had its game against Ringgold canceled Thursday due to an alleged incident involving some of the Rams players. Meanwhile, McKeesport flexed its muscles in a 28-7 win at Mars, and West Allegheny cracks the top five for the first time after a 32-8 win over New Castle.

Avonworth defeated McGuffey, 41-13, Central Valley scored a 52-20 win at Quaker Valley and Beaver blew out North Catholic, 48-10.
