Medical examinations revealed Hazlewood, 34 avoided tissue injury. The uncapped Abbott, 33, suffered a moderate-level injury

Like many of the Australia players, Hazlewood participated in the current round of state games building up to the Ashes

Abbott earned 57 international selections for Australia in limited-overs formats
