India's Gill in doubt for first Test after thumb blow

India's top-order concerns have been compounded, with fears Shubman Gill will miss the first Test against Australia in Perth with a thumb injury.

Media were locked out of India's centre-wicket training session at the WACA on Saturday, but Gill is believed to have suffered the injury while fielding in the slips.

Multiple media reports from India have since confirmed Gill is now in serious doubt for the first Test starting in Perth on Thursday.

The reports suggested Gill was more likely to play in the second Test in Adelaide on December 6.

Any injury to Gill would come as a serious blow to India, with opening batsman and captain Rohit Sharma yet to touch down in Australia due to personal reasons.

KL Rahul also suffered a blow to the elbow at training on Friday, but is expected to be fit to play at Optus Stadium.

If Gill and Sharma are to miss the match, India could be forced to hand a debut to Abhimanyu Easwaran in Perth, with their batting options running low.

India have already arrived in Australia under scrutiny, after suffering their first ever 3-0 series sweep at home when beaten by New Zealand in the past month.
