Ghana striker Abdul Majeed Waris held his first training session with Lorient ahead of his debut against Lyon on Sunday.
The 23-year-old had been expected to join Rennes in a $4.4m (£2.82m) deal from Turkish side Trabzonspor.
But at the last hour Lorient trumped their rivals' bid to snap up the Black Star, who has 19 caps for his country.
Waris previously played in France for Valenciennes in 2013/14 where he scored an impressive nine goals in 16 games.
