Onuora is in charge of the first team in Jackson's enforced absence (PA)

Jackson is away from Sincil Bank getting treatment for throat cancer and Onuora says Tuesday's 1-0 derby win at Notts County was a big boost for him.

"We've still got him more than in the back of our minds," Onuora said.

"It's a big fillip for him - every result like this gives him a boost," he told BBC Radio Lincolnshire.

He added: "We're edging to where we want to be which is in the top half of the table and we will push on from there."
