Ankle injury sidelines Sam Jacobs for clash with Brisbane

Adelaide ruckman Sam Jacobs has been ruled out of this week's clash with Brisbane due to an ankle injury.

Jacobs rolled his ankle during the Crows' 82-point win over Essendon on Sunday and sat out the second half of the match.

“Scans on Sam’s ankle have confirmed a low-grade ankle sprain, which will keep him sidelined for this week,” General Manager of high performance Brett Burton said.

“Fortunately, the injury isn’t serious. Sam will be re-assessed next week and is a chance to play against Fremantle.”

It is the first match Jacobs will miss since 2012. he has played 93 consecutive matches.

Meanwhile, veteran midfielder Scott Thompson will also miss the match, with the club opting to rest the 33-year-old in the lead in to the finals.

Crows' coach Don Pyke also confirmed on Wednesday that young 201cm ruckman Reilly O'Brien will come into the side to make his senior debut to replace the injured Sam Jacobs.
