Striker links up with Owls on youth loan.
Connor Wickham has returned to Sheffield Wednesday for a second loan spell.
The 20-year-old striker spent time with the Championship side last season, making six appearances and scoring once.
Wickham will remain with Wednesday until January 1 and could make his second debut for the Owls against Reading this weekend.
The England U21 international joined Sunderland from Ipswich in June 2011 and has made 40 appearances for the club.
