Kevin Lisbie remains an injury doubt for Leyton Orient ahead of Saturday's visit of League One rivals Hartlepool.
The experienced striker had to go off with a nasty head injury after he was caught by a stray arm from Rochdale defender Pim Balkestein during Saturday's 2-0 win.
"Kevin was knocked out," said manager Russell Slade.
"You can see on the DVD he goes down like a heavyweight boxer, he was sparked out.
"He might be a doubt for Saturday, we'll see."
