Birmingham have extended Scott Sinclair's loan spell from Chelsea until the end of the season.
The 19-year-old winger initially joined Blues on a month-long deal in early January but he has impressed manager Alex McLeish.
Sinclair has started three games already and made a further appearance as a substitute.
He provided the cross for Kevin Phillips' equaliser on Saturday as Birmingham snatched a last-gasp 1-1 draw against Sheffield Wednesday.
Sinclair will hope to continue his fine form as Birmingham challenge for promotion to the Premier League.
Birmingham are currently third in the Championship table, two points adrift of Reading and six behind leaders Wolves.
