The winger has joined the Latics on a month's loan.
"I think he had to go out and play," said Lambert.
"To be fair he's not really kicked a ball in earnest for a year or so due to his injuries.
"I just thought it was the right thing for him and for us to try and benefit from him getting out there and playing some games.
"Hopefully that spell at Wigan will help him. It gives him game time quicker than he will get here and I think that was important."
