There are doubts over wicketkeeper batsman <a href="https://www.cricketcountry.com/players/Jonny-Bairstow/">Jonny Bairstow</a> s participation in the fourth ODI between <a href="https://www.cricketcountry.com/teams/England/">England</a> and <a href="https://www.cricketcountry.com/teams/Sri-Lanka/">Sri Lanka</a> in Pallekele on Saturday. During a practice session where the England team was engaged in a game of football, Bairstow suffered an injury to his right ankle which makes him a doubtful starter. He will have to undergo a fitness test early on Saturday to get a clear picture over his availability. <p></p> <p></p>If Bairstow s injury doesn t heal by tomorrow, he will be taken for scans in Colombo on Sunday. In his absence, <a href="https://www.cricketcountry.com/players/Alex-Hales/">Alex Hales</a> is a strong replacement option for England at the top. Bairstow, who has been opening the innings in the ongoing series alongside <a href="https://www.cricketcountry.com/players/Jason-Roy/">Jason Roy</a>, completed 1000 runs this calendar year during the second ODI, making him the sixth English cricketer to do so. <p></p> <p></p>Allrounder Joe Denly, who joined the squad as a replacement for injured spinner Liam Dawson, could also be in line to replace Bairstow should he not be cleared to play. Denly himself knows a thing or two about injuries for he had suffered a knee injury while playing football in 2009, after which the then England coach Andy Flower had banned the sport as a warm-up game for England cricketers. <p></p> <p></p>"A few of the lads were saying I ruined their football - the best part of the day as they say. Thankfully it is back in now and hopefully no more injuries," Denly said. <p></p> <p></p>England lead the series 2-0 and have a chance to secure a series win on Saturday.
