Director Richard Montague said: “Right up to the end of the transfer window we were interested in adding another attacking option to the squad and, following the long-term injury to Curtis Edwards and with Jodi Jones continuing to be assessed, we felt it was important to take action.
“To have the opportunity to sign a player of Josh’s pedigree at this stage of the season is fantastic.
“While he predominantly plays as a winger, we think he has the technical ability to also play more centrally in our system.
“We have every confidence he can make a positive impact for us between now and January, when this deal expires.”
