Leyton Orient boss Russell Slade has admitted that he does not yet know the extent of the shoulder injury that Kevin Lisbie suffered against Bristol City.
The striker was forced off at Ashton Gate on Tuesday night as Orient drew 0-0 with the Robins in League One.
"Kevin Lisbie's shoulder popped out and then back in again, which is very painful," Slade told Sky Sports News. "We'll have to wait and see how it settles down."
Orient return to action on Saturday when they entertain Walsall in the league.
