Howard, now 35, made his Carlisle debut and saved a penalty against Tranmere at the weekend, but couldn’t avoid his side suffering a defeat that sent them second bottom of League Two.
Gavin Skelton, United’s caretaker manager, said of Howard: “I’m happy with his debut and he’s an influence on the dressing room.
“It was very harsh on Lukas Jensen. He’s a good ‘keeper who’ll have a good career. We’ll have a look at that for the next few games but he has a presence about him which can help the back four.
“Picking him was just a case of bringing that experienced core to the team – that talking. Before the game he was talking to the lads, shouting, and you could hear that during the game.
“No reflection on Lukas, he’s disappointed, but it’s just bringing that experienced ‘keeper and voice in.
“He’s come into the dressing room and has a confidence and presence about him, which perhaps we need to add to the team.”
“We wanted to bring him in because it’s just bringing that experienced core to the team, and the way he’ll talk to the players around him,” Skelton added.
“Lukas is not best pleased, which I understand, and that’s part of football. If you’re not playing, you’re not happy, and he’s one who will have a good career.”
