Leicester Tigers started well with great defending and two brilliant tries from Adam Radwan and Ollie Hassell-Collins, giving them a 15–6 lead.
Leinster had problems early on — Tadhg Furlong was sick before the game, and they lost Jack Conan and Jimmy O’Brien to injuries in the first 15 minutes.
But their star-filled team, including several Ireland internationals and New Zealand’s Rieko Ioane on his first start, eventually settled and fought back.
In the second half, Leinster completely took control, scoring 17 unanswered points. Tries from Jamison Gibson-Park and Dan Sheehan sealed their second win in two Champions Cup pool games.
Leicester, however, have now lost both of their opening matches in Pool Three and will struggle to qualify for the last 16.
Leinster, four-time champions and regular contenders, had to work hard for this win. The first 20 minutes were chaotic: two injuries, a disallowed try, and a scuffle after James Lowe was tackled in the air.
Radwan then scored a stunning full-length try, kicking ahead several times and outrunning everyone. Just before half-time, Hassell-Collins added another after controlling a crossfield kick.
But in the second half, Leinster finally made their pressure count. Gibson-Park reacted quickly to a loose ball and scored, Harry Byrne added points with the boot, and Sheehan powered over from a line-out drive to finish the comeback and deny Leicester a bonus point.
