Yet Wilson hopes it is only a temporary measure, telling the club's official website: "The talks are ongoing with Leeds about Alan. We're not too sure about how they will pan out at this stage, but we're hoping he'll be available for Saturday.
"It's a similar thing with Danny and we're talking about extending that too, so we'll have to hope Bolton let him go out again.
"But with a bit of luck they'll both be available on Saturday for the game at MK Dons."
On-loan striker Alex Revell also returned to Southend on Monday but Wilson has re-iterated that he will not be looking to bring him back as he could not guarantee regular football. Meanwhile, Robins defender Sean Morrison is expected to return from his loan spell at Southend early next week.
