Australia have added seamers Gurinder Sandhu and Kane Richardson to their squad for the Tri-Series against England and India.
Sandhu, 21, is uncapped while Richardson, 23, played the last of his eight one-day internationals in November.
The pair are not part of the 15-man World Cup squad named yesterday but are on hand for the first part of the preparatory series to give the likes of Mitchell Starc, Josh Hazlewood and Mitchell Johnson the chance to rest.
Johnson is not expected to feature until Australia's third match, versus England in Hobart on January 23.
A Cricket Australia statement read: "Given the heavy workloads undertaken by Mitchell Starc and Josh Hazlewood during the fourth Test, and the hamstring problems recently suffered by Perth-based pair Mitchell Johnson and Mitchell Marsh, the selectors have named South Australia's Kane Richardson and New South Wales seamer Gurinder Sandhu as extra bowling options for the early matches of the Tri-Series."
