Ashton Turner has been added to Australia's one-day international squad as cover for an ill Mitchell Marsh.

Marsh will miss the opening game of the three-match series against India on Saturday due to gastritis.

The all-rounder may feature in the final two games, but Turner – who has played three Twenty20s for Australia – has been called up as cover.

"He can finish the innings off well, an elite athlete in the field and he's also a captain," Australia coach Justin Langer said.

"You see the way he finishes off an innings that he's a good thinker of the game like most of the great finishers and a really good leader, good person around the group.

"I'm very excited to see him come in."

It continues a rough week for Marsh, who was dropped from Australia's Test squad for the series against Sri Lanka due to poor form.
