The Cavan hurlers now have two defeats from as many games after losing 4-16 to 1-10 to Leitrim at Kingspan Breffni.
Leitrim led 2-5 to 1-6 at the half-time break; Brendan Delaney and Sean Markham with Leitrim’s goals while Sean Keating found the net for Cavan.
The visitors moved 11 points clear with as many minutes remaining when Diarmuid Kelleher found the net before Brendan Delaney added his second goal four minutes later as Leitrim ran out convincing winners.
The result leaves Cavan second from bottom of the table and they'll be hoping for their first victory of the campaign next week when they play basement side Lancashire.
