GEELONG veteran James Kelly is likely to be sidelined for at least three weeks in a best-case scenario after suffering a high ankle sprain in the win over Port Adelaide on Friday night. 

The triple premiership player could be missing for up to eight weeks, however, with scans this weekend to reveal the extent of his injury. 

Kelly had to be subbed out of Friday night's clash early in the first quarter after being hurt in a tackle laid by Power midfielder Ollie Wines.

He returned to Melbourne on crutches on Saturday afternoon. 

"It's a high ankle sprain, I think, but as to how bad it is, we're not sure yet," Kelly told the club's website on Saturday. 

"If it's a good one it could be three or four (weeks), if it's a bad one it could be six or eight (weeks).

"We're not too sure. We'll know by Monday." 

Five talking points: Port Adelaide v Geelong

Ruckman Rhys Stanley will also have scans over the weekend after he suffered a foot injury in the 23-point win over Port.

"I can't comment on what's wrong with him," Kelly said.

"I'm not sure, so we'll wait and see."

Stanley was playing the match of his career (17 disposals, two goals, 24 hit-outs, six clearances) when he was forced from the field late in the third term.
