The Dutchman sustained a hamstring problem at the tail end of Sunday's victory over Norwich.
It was feared Krul would at least miss this weekend's trip to West Brom, but scans identified there was no major damage to his muscle tissue.
The 23-year-old will therefore now hope to take his place in Pardew's line-up at The Hawthorns, where Newcastle will aim to reinforce their hold on sixth place in the Premier League.
Krul said on Twitter: "Just had result back of the MRI scan.. All clear.. Already looking forward."
