Indian all-rounder Ravindra Jadeja is likely to miss the opening Test against Australia owing to the concussion and a hamstring injury that he sustained during the opening T20 International in Canberra.

The 32-year-old, who is on the cusp of his 50th Test, is likely to be out for at least three weeks which certainly rules him out of the first Day/Night Test in Adelaide starting December 17. In case it turns out to be a hamstring tear, it could well rule him out of the second Boxing Day Test in Melbourne from December 26. "As per ICC's concussion protocols, after any head injury, a player needs to be rested for 7 to 10 days, which effectively rules Jadeja out of the three-day day/night warm-up game at the SCG from December 11," a BCCI source told PTI on conditions of anonymity.
