The 29-year-old is set for a spell on the sidelines after suffering a calf injury in the 1-1 draw against Manchester United at St James’ Park last month.
It is not yet clear how long Wilson will be out for, but the former England international admitted ‘this one is probably middle of the road’ between a niggle and a bad injury ahead of seeing a specialist on Friday.
Dwight Gayle, who has made just one substitute appearance under Eddie Howe, is Newcastle’s only natural fit striker and Wilson knows that the Magpies are looking to bring in another goalscorer this month.
“People are going to be coming in the door,” he told the Footballer’s Football podcast. “There’s no doubt about that. We’re going to add bodies to our squad. It’s one of those things.
“The January window is always a tricky window. You want players that are coming in the door ready to help and add to the situation that’s already there, which, ultimately, at the minute, is a relegation battle unfortunately.
“You want players that are up to the challenge, that are not just coming for a quick pay day because they want to come back to the Premier League and be known or play for Newcastle or this and that.
“I think you have to get players in the door that are going to play for the badge first and foremost and, then, beyond that, we want to add quality. We don’t just want to add numbers. We don’t need quantity; we need quality.
“I think strengthening in a lot of areas is important. We have a great squad at the moment already, but we need help. We need assistance.
“As a striker, you want players that are going to have back-up in different areas and, also, challenge you as well.
“With me being out now, not having a timeframe, you’re also going to need someone to replace me in the short-term. I’m not going to say long-term because you’ve got to back yourself!
“We definitely need players. It’s down to the club and the recruitment guys to get in the right players and I’m sure they’ve done their research and due diligence on who they want in.
“Beyond that, we can hopefully stay in the Premier League and then build again in the summer, which is probably a better window to be shopping in.”
