Waghorn, a fans' favourite after his successful spell on loan under Pearson at Leicester in 2009, cites a recent hamstring injury as cause for his hasty return to the King Power Stadium. The ex-Sunderland striker was signed on a permanent deal by Paulo Sousa for £3 million but never made it into Sven Goran Eriksson's plans and he was shipped-out to the KC Stadium to rejoin Pearson.
With Pearson's return to Leicester and with Waghorn likely to remain injured until the New Year it was natural that the 21-year-old would return to the East Midlands.
"He has been brought back for assessment and he is going to get some treatment here because it was a lot more serious than first thought and it wasn't really repairing," said Foxes' assistant manager Craig Shakespeare, "We have had him scanned and we will treat him on a week-to-week basis here. He probably won't be fit before the loan finishes anyway."
Waghorn made five appearances during his temporary spell with the Tigers, scoring against Doncaster Rovers and earning his first call-up to the England under-21s along the way.
