Despite that setback, Boro again started the second half positively with Johnson trying his luck with a long-range effort before being replaced by Lee Cattermole after 53 minutes.
"We've had some tough days here this season and we got all the breaks in the first half, got some luck and executed very well, " Johnson told BBC Sport.
Meanwhile, wicketkeeper Haddin showed his good sportsmanship behind the stumps by indicating that an edge by Sehwag off Clark had not carried - while the right-hander rode his luck when he nearly chopped a low delivery from Johnson onto his stumps.
