It was a wild weekend of wild-card playoff games in the opening round of the NFL postseason.

The Washington Redskins lost rookie quarterback Robert Griffin III when he reinjured his right knee in the fourth quarter of their 24-14 loss Sunday to the Seattle Seahawks.

The Baltimore Ravens ensured retiring star linebacker Ray Lewis will play at least one more game after disposing of quarterback Andrew Luck and the Indianapolis Colts 24-9 on Sunday.

Green Bay routed Minnesota 24-10 Saturday night in a rematch of their regular-season finale, and did not let 2,000-yard rusher Adrian Peterson run over them again.

The Houston Texans pulled out a 19-13 win over the Cincinnati Bengals on Saturday. Arian Foster gained 140 yards, becoming the first player with at least 100 yards rushing in his first three postseason games.
