‘Disappointing’ facing depleted Ireland
Cokayne could make her England return on Sunday after tearing her calf playing for Harlequins in February.
Lark Davies and Connie Powell have played in her absence, contributing to England’s domination of the tournament so far.
The Red Roses – who are seeking a fourth successive title – have claimed three bonus-point wins in which they have scored a total of 189 points and conceded just 10.
They face an Ireland side who have won one of their three games and who will be without a large part of their squad with seven players balancing the XV-a-side game with sevens duties and two absent through injury.
Cokayne said facing such a reduced side is “quite disappointing”, adding: “You want to be playing the best.
“You don’t want to play a team that is severely depleted. For whatever reason they can’t really control that with scheduling.
“With England we’re quite fortunate in that our sevens and XVs programmes are quite separate now so we don’t have those kind of issues.”
