Johnny Sexton will be carefully managed ahead of Lions tour

Stuart Lancaster insists Johnny Sexton will be carefully managed throughout the business end of a season that concludes with the British and Irish Lions' tour to New Zealand.

Sexton will return to Leinster's starting XV for their Champions Cup quarter-final against Wasps at the Aviva Stadium on Saturday in his first appearance since helping Ireland deny England back-to-back Grand Slams.
