Brest made a pair of loan signings on Tuesday, with Auxerre striker Issam Jemaa and Udinese midfielder Abdou Sissoko joining until the end of the season.
Auxerre confirmed they were allowing Tunisia international Jemaa, 28, to move to their Ligue 1 rivals after he has struggled to secure regular first-team football following his move from Lens last summer.
"Issam Jemaa will join Stade Brest for the rest of the season in Ligue 1 with an option to buy," a statement on their website read.
Jemaa is currently at the African Nations Cup, where he has scored once as Tunisia have sealed their place in the quarter-finals with a match to spare.
Brest confirmed the signing of Sissoko on their website this afternoon.
The 21-year-old came through the ranks at Troyes before moving to Italy last summer.
