The 24-year-old Karnataka missed third Test match at Mohali after sustaining injury on his finger during Vizag Test.
Rahul's come back into the Indian side means he'll be opening the innings with his regular opening partner Murali Vijay.
Rahul has had a phenomenal batting performance in 2016, but he couldn't perform as expectated in the last two Test matches. He has scored 32, 38, 0 and 10 in the last 4 innings.
These numbers certainly do no justice to his potential and talent and the youngster would be hoping to improve his figures.
After the drawn first Test where Indian batting came under scrutiny in the second innings, Rahul was pulled out of an ongoing Ranji Trophy match against Rajasthan to be brought into the Indian team.
Skipper Virat Kohli has already termed him team's No.1 choice opener. With Rahul becoming an automatic choice, it seems to be curtains for veteran Gautam Gambhir's Test future, who made a Test comeback after more than two years.
In Rahul's absence, wicketkeeper Parthiv Patel opened the Indian innings at Mohali. The left-handed batsman will now be playing in the middle order at the expense of young Karun Nair.
Nair made his Test debuted at Mohali but was unlucky to get run out and thus had a forgettable debut game.
Parthiv was given a Test call up after a gap of eight as a replacement to regular glovesman Wriddhiman Saha, who injured his thigh.
Rahul, golfer Aditi Ashok and Bengaluru Football Club walked away with top honours at the ACT-Sports Writers' Association of Bangalore (SWAB) awards on Sunday (December 4).
Rahul enjoyed a breakthrough season - he became a regular opener across formats for India and had a splendid Indian Premier League season for Royal Challengers Bangalore.
