Goal challenge for Rovers defender
The centre-back ensured Rovers won for the first time in eight matches when he headed home five minutes from time against Peterborough to put the South Yorkshire club 3-1 in front.
It was Shackell's first goal since arriving at the Keepmoat Stadium on loan from Wolves.
O'Kelly told The Star: "Jason should score more goals. He heads the ball more than anyone on the pitch but he doesn't get on the end of enough set-pieces in the box and that is something that he's got to add to his game."
