* C.H. Flowers at Suitland, 2 p.m. Saturday: Unbeaten teams have clinched playoff spots and enter tied for the Prince George's 4A league lead, but plenty remains at stake. This game likely will decide the league title and the top seed in the Maryland 4A South Region playoffs, which could be significant because the loser seems likely to face Eleanor Roosevelt in the first round of the playoffs.

Flowers is enjoying the best start in its four seasons of varsity competition, relying on a potent offense featuring RBs Brandon McRae, Ramond Dixon and Jimmy McClam. The Jaguars have been held to fewer than 28 points just once this season.

Suitland is led by running back Navarro Bowman and wide receiver Mark Duncan, talented players capable of breaking long plays. This will be the Rams' first game against a team with a winning record since Sept. 11.

* Calvert Hall at Gwynn Park, 2 p.m. Saturday: The second game in a difficult three-game stretch for the Yellow Jackets, who last week defeated Forestville and next week play rival Douglass. Calvert Hall is only 3-4, but it has lost three games by less than a touchdown to opponents (St. Johns, Douglass, McDonogh) that have a combined four losses.

* Eleanor Roosevelt at Northwestern, 2 p.m. Saturday: The Raiders have won three consecutive games with ease and could be primed to make a strong run in the postseason. The addition of QB Nico Scott and RB Malcolm Banks two games ago gives Roosevelt a pair of top-notch skill players to go along with Derrick Williams, allowing Williams to move from quarterback to wide receiver on occasion.

In two games since Scott and Banks were cleared to play after an investigation into their transfers, Raiders have totaled 85 points. TE Will Davis is becoming a big-play receiving target.

Northwestern's defense has been stingy during its four-game winning streak, allowing just 31 points.

* Oxon Hill at Laurel, 2 p.m. Saturday: Don't look now, but after three consecutive one-victory seasons, the Clippers are in position to make a push for their first playoff berth since 1996. RB Raymond Saunders has emerged as a key player for Oxon Hill. After being shut out in their first four games, the Spartans have scored a touchdown in each of their past three games, but they have yet to lead in a game this season.

* Potomac at Forestville, 2 p.m. Saturday: Probably the last real test in the regular season for the Wolverines, who are trying for their first undefeated regular season since 1996 and their third under Coach Eric Knight, who previously coached at Forestville.

The game will feature several of the Washington area's top linemen -- Forestville's Antonio Logan-El and Rashad Maybin and Potomac's Gus Parrish, Brandon Jackson and Reggie Berry -- and such top skill players as Forestville's Jermaine Lindsay and Potomac's Korey Coles.

Potomac won both of the team's meetings last season, 14-6 in the regular season and 50-27 in the playoffs.
