Milton Nunez was the only real big-money signing on transfer deadline day as Sunderland paid £1.6m for the 27-year-old Honduran.
Nunez joins from Greek First Division side PAOK Salonica although the transfer fee will go to his former club Nacional of Uruguay.
They could net a further £1m depending on appearances.
Nunez has secured a work permit and is eligible to play against Everton on Saturday.
He was spotted by Sunderland's chief scout Andy King in the New Year while
playing in Miami in the America's Gold Cup.
"He has something I thought we were missing, that bit of extra pace up front and I'm looking forward to seeing what he can do for us," said Sunderland manager Peter Reid.
