Keaton Jennings hit an impressive century on his international debut as England reached stumps on day one of the fourth Test against India on 288-5. The Johannesburg-born Durham opener, drafted in for Mumbai as a replacement for the injured Haseeb Hameed, finished the 2016 County Championship as Division One's top scorer with 1,548 runs at an average of 64.5 and he continued that stellar form at the Wankhede Stadium with a classy 112.

Former South Africa U19 skipper Jennings, the 11th different batsman to partner captain Alastair Cook at the top of the order since Andrew Strauss' retirement in 2012, is the 19th England player in history to register a ton on his maiden appearance and the first since Jonathan Trott hit a second-innings 119 against Australia at the Oval in the final Test of the 2009 Ashes series. He is the eighth opener to achieve the feat.

"It's been an incredible six to eight months and an even more special 72 hours – meeting the guys and getting a hundred," Jennings told Sky Sports at the end of play. "There was a little bit of panic at 5am this morning when I woke up and thought I'd missed the bus, but it has been awesome. I settled down after scoring my first run and Cookie helped me.

"You never know if your game is ready for Test cricket and how you will react under pressure – thankfully I have done well straight away but you have to sustain it over a long period of time. Happiness outside of cricket has certainly helped me, making me a little more positive and relaxed."

England, who trail the five-match series 2-0, were one run shy of the 100-mark when Cook was disappointingly outfoxed by Ravindra Jadeja and stumped by Parthiv Patel for 46. Despite that, however, the tourists went in at lunch sitting pretty on 117-1 with Jennings not out on 65, having been dropped in the gully on 0.

Joe Root later fell for 21 after Virat Kohli took an excellent catch off the bowling of Ravichandran Ashwin at slip and umpire Paul Reiffel, a former Australia international, retired hurt and was taken to a local hospital after accidentally being hit on the back of the head by an errant looping throw from Bhuvneshwar Kumar intended for Cheteshwar Pujara while standing at square leg. He was attended to by the England physio and received further treatment in the dressing room after being replaced by third umpire Marais Erasmus. A CT scan came up clear and he was subsequently advised to rest.

Jennings went on to seal a memorable century with a confident reverse sweep and steered his side to 192-2 at tea. Moeen Ali added 50 from 102 deliveries, but instigated a familiar collapse when he threw his wicket away with a big top edge off an attempted sweep that was caught by Karan Nair. Ashwin claimed his second dismissal in just three balls when Jennings edged through to Pujara stationed at gully.

Ashwin struck again to remove Jonny Bairstow, who mustered 14 before his own top edge fell for Umesh Yadav. Ben Stokes dug in and survived an umpire's review after being hit on the pads by Jadeja. The feisty all-rounder reached the close of play on 25, with Jos Buttler still there on 18.

Stuart Broad has not been deemed fit enough to return to the fold as he continues to recover from a foot tendon injury suffered during last month's 246-run second Test loss in Visakhapatnam and his place in the team has been taken by Nottinghamshire teammate Jake Ball. The right-arm paceman was chosen ahead of Steven Finn and Hampshire's Liam Dawson.
