Spearing looks set to be handed the job of filling in for Lucas who has been ruled out for the remainder of the season after damaging knee ligaments in last week's Carling Cup win at Chelsea.
"It's up to someone else now to come in and try to do as good a job as Lucas was doing," Carragher said. "That won't be easy as he's been as good as anyone in that position in the Premier League this season.
"But Jay Spearing was outstanding towards the end of last season. He was superb in our win at Fulham.
"In the Carling Cup this season he's also done really well. He has started away to Stoke and Chelsea - that's two of the toughest away games you can get in the Premier League. He's performed well and we got good victories in both of those Cup games.
"No-one will be worried one bit about putting Jay in there. He's proven before that he's more than good enough at this level and I'm sure he will prove it again."
