It happened on the N2 on September 11th.
Gardai have renewed their appeal for witnesses to a fatal crash in County Louth on September 11th.
It involved a motorbike and a car on the N2 near Dooley's Pub at about half past eight that evening.
The motorcyclist suffered critical injuries and died two days later.
Officers say it's very likely that Tyrone GAA supporters were using the road the night of the crash, as the All Ireland football final was on earlier that day.
Gardai in Ardee are calling on anyone who was travelling on the N2, or who has footage of the road, between 8pm and 8.30pm that night, to come forward.
