Lancashire director of cricket Paul Allott said: "We are very fortunate that we’ve been able to find a replacement for Glenn as he leaves us to meet up with the Australia World Cup squad.
"Getting a player of quality for a short spell, with little notice can be difficult, but we’re really pleased that we have been able to secure the services of Jake for the rest of the competition.
"Everyone at Lancashire Cricket wishes Glenn all the best for the World Cup and we look forward to welcoming him back to Emirates Old Trafford later this summer for our Vitality Blast campaign and remaining Specsavers County Championship fixtures in September."
