Caelan Doris says he is in a "much better place" than this time last year having missed the 2021 Six Nations due to concussion symptoms.
Doris' Test career started on a worrying note when he suffered a concussion just four minutes into the 2020 Six Nations in his championship debut against Scotland.
Then he stood down from Ireland duty before last year's championship having suffered further symptoms in a training game with Ulster.
