Shoulder injury for Blues' star Weitering

It was checked by Blues medical staff on the bench for a few minutes before they took Weitering down to the change rooms for further assessment.

The substitution was made almost immediately, with young forward Jack Carroll called into the game.

All-Australian defender Weitering's absence leaves a huge hole in Carlton's back-line.

The Blues are aiming to win a fifth-straight game that would further entrench them in the top four on the ladder.
