T20 World Cup: Australia Calls Up Steve Smith Amidst Captaincy Uncertainty

• Australia makes a significant change to its T20 World Cup squad ahead of a crucial match against Sri Lanka.
• Steve Smith has been included in the team as a replacement for fast bowler Josh Hazlewood.
• Smith was initially a backup for captain Mitchell Marsh, who sustained an injury during practice.
• Marsh missed the first two matches, and there's uncertainty about his and Marcus Stoinis's fitness.
• If Marsh is not fully fit, Smith's inclusion and potential captaincy are on the cards, despite low chances for today's playing XI.
