Leyton Orient boss Martin Ling admits plans to sign Birmingham City defender Sam Oji are up-in-the-air following Steve Bruce's departure.
"But things are up in the air now, because we don't know who is going to be in charge of the club and Sam may fancy going back there and trying to win over a new manager.
"We have still got him with us until November 28, but we will need someone else in if he goes back because I don't want to be left with just three central defenders going into the busy Christmas period, especially as Alton Thelwell is already playing with an injury."
