All eyes were on Anderson on the fourth morning of the third Test at the Ageas Bowl, as the 38-year-old looked to make a couple of breakthroughs with the new ball and become the first pace bowler in history to reach the magical 600 mark.
He had already taken 5-56 in the first innings to leave Pakistan following on, but openers Shan Masood and Abid Ali reached 41 for nought before rain forced the players off after just 18 overs.
Anderson was midway through his third of the day when he hung one a little wider outside off stump and invited a wayward drive from Masood. The ball clipped the outside edge sailed cleanly to wicketkeeper Buttler, who made a mess of a regulation chance.
The 38-year-old seamer reacted with a disbelieving shrug, having already watched three chances go down in the space of 10 deliveries on the third evening. He took a breather after five tidy overs which cost just nine runs - four of which came from a James Bracey overthrow.
The Gloucestershire man was on the field as an injury replacement for Ollie Pope, who sustained an injury to his left shoulder early in the session and was being assessed.
England captain Joe Root used four bowlers before the weather turned, forcing an early lunch break, with Jofra Archer and Chris Woakes tidy but unobtrusive in their first-change spell.
Abid was leading the scoring, unbeaten on 22 with Masood on 13. He had been stood down from opening duties on the third evening, with skipper Azhar Ali opting to continue after finishing the first innings 141 not out.
After play restarted at around 3.45pm, Anderson kicked things off but, despite knitting together a couple of typically testing overs, it was Broad who got England going in the fifth over of an elongated evening session.
Masood was his victim, offering no stroke to one that went across him but held its line enough to rap him on the pad. Michael Gough was persuaded to raise the finger and a DRS review showed it clipping off stump, with the batsman gone for 18 and Pakistan 49 for one.
