Krul suffered ankle ligament damage in the last-16 clash in Kharkiv against Metalist back in February, and has been missing in action since.
Krul is back in light training and is aiming to be in training at the beginning of April.
And that puts Krul in with a shout of the second leg of the Europa League quarter-final with Benfica on April 11 – not to mention the Tyne-Wear derby a few days later.
