Campbell on top form
Donegal made it two wins from two as they defeated Louth in Letterkenny.
Louth were a point ahead at the break -- 2-6 to 1-8 -- but Donegal hit a purple patch in the second half to register seven unanswered points to establish a comfortable cushion.
Wesley Morrissey scored the opening goal for Louth on 15 minutes, while Gerard Smyth smashed home a penalty just before the interval.
But Niall Campbell proved the difference as he hit a spectacular goal on 20 minutes to get them back on track after Louth and he was also accurate from frees.
And even though they lost centre-back Joe Boyle to a second yellow card with 12 minutes left and Louth grabbed a goal from Shane Callan on 63 minutes, the hosts held on.
