Massimo Maccarone will be in Portugal with the rest of the Middlesbrough squad for the game tomorrow against Sporting Lisbon.
The sudden return has taken place as a proposed extension to his loan to Siena (Italy) broke down. Last season Macarone went on loan initially to Parma and made nine appearances (six starts) without scoring.
He then moved on to Siena where he scores seven from eight starts and nine sub appearances.
