Fermanagh boss Peter Canavan was impressed by the effort put in by his players in the 2-12 to 2-6 win over Roscommon at Brewster Park.
"It was a good display and the boys were very committed but we are not getting carried away after two wins," said Canavan.
"We only have three home games in the league this year so it is imperative that we win them.
"We scored some great points in the game and I'm pleased plenty of players were on the scoresheet."
Sean Quigley helped himself to seven points – some of those from the very top drawer of dead-ball kicking from the hand and from the floor – as Fermanagh coasted to victory by a six-point margin.
Canavan's side now top the table as the only undefeated team in Division Three.
Cavan and Monaghan resumed their own local quarrel in the same division.
Gavin Doogan, Dessie Mone and Conor McManus were all sent off as Monaghan fell from a 12-point win over Meath last Sunday to an eight-point loss – 1-10 to 0-5 – to Cavan, who also had Martin Dunne and John McCutcheon dismissed.
Kerry followed an awful scoreless second half last week in their defeat to Mayo with a 10 point loss – 1-11 to 0-4 – against Dublin in Killarney.
The Dubs now top the Division One table along with neighbours Kildare, who benefitted from late goals from Niall Kelly and Paddy Brophy to nick a 2-10 to 1-9 win away to Cork.
Kieran McGeeney's charges look well placed to establish themselves in the top flight after their encouraging start.
The National League match between Armagh and Wexford scheduled for the Athletic Grounds on Sunday was postponed due to a waterlogged pitch.
Another Division Two fixture, Louth's game against Galway, was also off as the Drogheda venue was unplayable.
