ADELAIDE superstar Eddie Betts is extremely confident club champion Rory Sloane will pass a series of concussion tests and be cleared to face Geelong at Adelaide Oval on Friday night.

Sloane was knocked out in the third quarter of the Crows' 46-point victory over Melbourne in Darwin last Saturday night. 

"I think Rory will play," Betts told Adelaide radio station FIVEaa on Tuesday morning. 

"He's acting really good around the club. 

"I don't know what you have to do to play this week because I haven't been concussed, but he is going to have to pass a couple of concussion tests. 

"I'm pretty sure he'll play." 

The Crows could give Sloane up to the morning of the game to prove his fitness for the top-of-the-table clash with the Cats. 

Sloane brushed aside the Crows' medical staff so he could play on, but Betts and skipper Taylor Walker showed great leadership in convincing him to leave the field.

"It was weird to see one of your leaders go down like that and to react like that," Betts said. 

"If you know Rory, he's a warrior and he wants to get back out and give himself for the team. 

"He got up, done a little skip, but he had to go off because they called for the stretcher and the game wouldn't go on if he didn't go off. 

"Tex came over and said 'just go off'."
