Between Newcastle and Boro, they have won only three times in 40 league games, and only victories will now do.
Shearer's plans continue to be disrupted by injuries, with his only left-back, Jose Enrique, likely to miss out once again.
He has problems too in midfield with Barton suspended and Alan Smith struggling to shake off a thigh problem, although that could provide an opportunity for other members of his squad.
Shearer: "There's Danny Guthrie, Kevin Nolan and Nicky Butt.
"We will be hoping that Alan Smith is okay, but he's going to be touch and go.
"But, like the rest of the players, they won't need motivating for this game.
"They will be able to go out there and feel the atmosphere. It's all up to us to try to go out there and get that win."
