A formula to supply players for the new Minneapolis Vikings and the problem of increasing the 1961 schedule to fourteen games will be discussed by National Football League owners at a meeting at the Hotel Warwick today.

Other items on the agenda during the meetings, which are expected to continue through Saturday, concern television, rules changes, professional football's hall of fame, players' benefits and constitutional amendments.

The owners would like each club in the fourteen team league to play a home and home series with teams in its division, plus two games against teams in the other division. However, this would require a lengthening of the season from thirteen to fourteen weeks.

Pete Rozelle, the league commissioner, pointed out:

``We'll have the problem of baseball at one end and weather at the other.''

Nine of the league's teams play in baseball parks and therefore face an early season conflict in dates.
