COLOMBO:- Angelo Mathews' hamstring injury will keep him out of the forthcoming T20 series in Australia, Sri Lanka Cricket has confirmed. A stand-in captain is expected to be named on Tuesday. Mathews has been in Sri Lanka since he sustained the injury during his match-winning innings in the second T20 against South Africa. Dinesh Chandimal took the reins in the final T20 of that series, before Upul Tharanga assumed interim leadership of the ODI side.–Agencies
