Washington stayed undefeated, edging Kansas City- Omaha and Houston before victimizing Milwaukee two nights in a row.

WFL: The league office upped the number of teams that will appear in the postseason playoffs to eight, which means that of the 10 teams still in the league, only two will be eliminated in regular-season play. And the two most likely candidates for elimination won last week.
