Broad, Watson injury doubts
Stuart Broad is expected to bowl in the warm-up ahead of the second day's play at Trent Bridge and, if he is deemed fit, will be able to return immediately for England. Australia may be down one bowler for the remainder of the Test, however, after Shane Watson suffered a "lower leg niggle".
Broad was unable to take the field on the first evening after taking a blow to his right shoulder from a James Pattinson bouncer when batting. Broad, who missed England's warm-up game at Chelmsford due to an injury on the same shoulder sustained while diving for his ground in the final of the Champions Trophy, spent the start of the Australia innings having treatment on the bruise.
An ECB spokesman confirmed that the new injury was not connected to the previous one - Broad was given a cortisone injection last week to reduce the inflammation and reduce the pain - and said there were no plans to send Broad for any scans or X-rays.
Watson complained of a problem while delivering his fourth over of the match on day one. The allrounder, who has a long and troubled history of calf problems, grimaced while bowling after lunch as Australia worked their way through England's batting. While he completed the over, he spoke with the captain Michael Clarke and did not bowl again in the innings.
Darren Lehmann, Australia's coach, confirmed that Watson had a problem, and was not entirely sure of whether he would be capable of bowling in the rest of the match.
"He's got a little but of a niggle, but he's going to see Alex Kountouris (the team physio) and I presume he's going to bowl in the second innings, but we'll let you know," Lehmann said. "It's just in the lower leg, so we'll just see how it goes."
Under Clarke's captaincy Watson has endured several recurrences of hamstring and calf ailments, most recently during the 2012 Boxing Day Test against Sri Lanka. After that match Watson informed the former coach Mickey Arthur that he intended to give up bowling for a time, and under Lehmann he has stated his desire to be a batting allrounder who only bowls a handful of overs each innings.
