Leyton Orient have signed Doncaster Rovers midfielder John Spicer on a month's loan.
As revealed by skysports.com earlier on Thursday, Orient have agreed a deal to sign Spicer before the close of the loan transfer window.
The 26-year-old former Arsenal trainee will go straight into Geraint Williams' squad for Saturday's trip to London rivals Brentford.
"John's a very good, versatile footballer," said Williams.
"He had a good upbringing, starting at Arsenal, and that's continued with Sean O'Driscoll up at Doncaster as well.
"We've seen in training that he's dying to get going and if he makes the team on Saturday I'm sure he'll bring that added dynamism and knowledge to us."
