The top three playoff spots in District 6-5A are decided, but there exists a chance that as many as four teams could tie for the for the final berth.
Euless Trinity, Colleyville Heritage and Hurst L.D. Bell have secured postseason passes in the nine-team district.
In fourth position going into Week 10 is 4-3 Grapevine, followed by three teams at 3-4: Haltom, Irving MacArthur and Richland.
Grapevine would clinch the fourth spot with a win over Richland on Friday. Richland would clinch by beating Grapevine if, as expected, MacArthur loses to district champion Euless Trinity on Thursday and Haltom loses to district runner-up Colleyville Heritage on Friday.
If Richland beats Grapevine and MacArthur and/or Haltom pull off upsets, the final berth would be determined by three- or four-way tiebreaker procedures.
Grapevine (5-4, 4-3) comes in having won three of four, including a 10-7 gut check over MacArthur last week, the difference being a 21-yard Nik Grau field goal. The Mustangs defense limited MacArthur to two first downs and 124 yards, 79 of which came on the Cardinals only touchdown of the night.
Richland (4-5, 3-4) has put itself in contention by winning its last two games, 28-6 over Haltom and 42-14 last week over Irving Nimitz as quarterback Walker Burns ran for 163 yards and three touchdowns.
Richland and Grapevine both missed the playoffs last year after losing in the first round in 2009.
