England found themselves a bowler down in the fourth Test against India after Stuart Broad retired hurt, having being struck on the nose by a bouncer while batting at Old Trafford on Saturday.
Broad, in the first over after lunch on the third day, hooked a couple of Varun Aaron bouncers for two sixes in as many balls.
But, trying to make it three in a row, he failed to connect with a bouncer timed at 88.1 miles per hour (141.8 kilometres per hour), the ball lodging between the peak of his helmet and the grille.
Broad immediately signalled for the England physiotherapist to come on and, after several minutes' on-field treatment, with blood coming out of a nose wound, walked off as he retired hurt on 12, with England then 338 for eight.
Broad did not resume his innings when new-ball partner James Anderson was ninth man out, with England thus 367 all out -- a first-innings lead of 215 runs.
Fast-medium bowler Broad, who took six for 25 as India were skittled out for 152 in the first innings of this match, remained off the field at the start of India's second innings, with his place taken by substitute fielder Liam Livingstone of Lancashire.
But with Livingstone not permitted to bowl, England found themselves a bowler light with all-rounder Chris Woakes given the job of sharing the new ball with local hero Anderson.
Earlier, England top-order batsmen Joe Root and Moeen Ali had also been unsettled by bouncers from Aaron, recalled for this Test by India with the five-match series all square at 1-1.
That was concerning for England ahead of next year's home Ashes series where they are set to face Australia fast bowler Mitchell Johnson, significantly quicker than Aaron.
Broad revealed after Thursday's first day close in Manchester he would undergo surgery on a longstanding right knee problem some time after the fifth Test against India at The Oval later this month, with a view to being fit in time for the one-day World Cup in Australia and New Zealand that starts in February.
