Sydney forward Gary Rohan will miss this week’s clash with Brisbane following a sickening collision during the Swans’ loss to Carlton on Saturday.

Rohan spent Saturday night at the Epworth Hospital in Melbourne after he was knocked out following a collision with Carlton defender, Sam Rowe.

The 25-year-old was running back with the flight of the ball and jumped to spoil Rowe, before clipping the Carlton defender in the air and falling awkwardly onto the ground.

He was discharged from hospital on Sunday after avoiding serious injury.

However, he will sit out this week with soreness.

“Gary is ok. His scans were all clear and he has a bad case of whiplash. He is going to be out this week,” coach John Longmire said on Wednesday.

Meanwhile, veteran Jarrad McVeigh, who has not played yet this season due to an ongoing calf injury, is a chance to return to the side.

“We are discussing at the moment whether we bring him straight in or he plays in NEAFL,” Longmire said.
