Crewe boss David Artell did not start Barlaser once in League Two and afforded him just 58 minutes of game-time via substitute appearances.
Upon the midfielder's departure, Artell reasoned: “I spoke to Dan and to Newcastle and explained that those ahead of him in the team didn't deserve to not be playing.
“Dan said he wasn't playing enough and I had to agree with him.
“It was just a question of those lads ahead of him doing well.
“Dan had done well but not well enough to get past Callum Ainley and Charlie Kirk.
“He played some Under-23 games for us and when I spoke to Newcastle about the situation, they thought it was better for him to return there and play Under-23 football for them.
“That was fine and it was all amicable.
“We all wish him well."
