India had four batsmen coming out to bat on the opening day of the second Test against Bangladesh, but none of them were dismissed, making it a rare instance of no wickets being lost in an entire day's play. India's score of 326 is the highest score among the instances when no wicket has been lost on the first day of a Test, going past Australia's 301 at Trent Bridge against England in 1989. It was also the first time India hadn't lost a wicket on the first day - on a complete day's play - of a Test.
Rahul Dravid has been involved in the last three instances when India have scored more than 250 runs in a day without losing a wicket - at Lahore in 2005-06, he added 258 on the fourth day with Virender Sehwag on the way to that 410-run opening stand, while in 2001-02 he combined with VVS Laxman on an utterly compelling fourth day at Kolkata, adding 335.
In terms of the number of runs scored on a day in which no wickets have fallen, India's effort lies in fifth place. The highest is 357, which has been achieved twice - by Sri Lanka against South Africa in Colombo last year, and by West Indies against Pakistan at Kingston in 1958. In third place is West Indies' 340-run effort against Australia, at Kingston again, in 1999, while the Laxman-Dravid stand at Kolkata is fourth.
India have now put together 73 century stands for the second wicket in Tests, and Dravid has been involved in the last 24.
Wasim Jaffer has scored less than 15 in 19 of his 35 Test innings. On the 16 occasions that he has gone past 15, he has gone on to at least a half-century 10 times. (Click here for Jaffer's inning-by-innings list in Tests.)
With both openers retiring ill, this was also the first instance in Test cricket of four batsmen combining to add more than 300 runs for the first wicket.
