Getting vectors into ZZZ at night at 10;000 feet; and 290 KIAS. Given a descent to 4;000 feet and a heading. Descended below 10;000 while still at 290 KIAS. I caught it at 9;000 feet; and immediately slowed to 250 KIAS using speed brakes. Controller did not say anything and we were not in proximity to other aircraft.Five hour ground stop in ZZZ1. Longer than usual flight plan with minor weather deviations. Was very tired; and this was only my second flight in three months. No Excuse! I think for sure fatigue and currency played a role; but I should not have made this mistake.Pay closer attention.
Air carrier Captain reported experiencing an airspeed deviation and cited fatigue and lack of recent flying experience as contributing factors.
