Scans have confirmed a low-grade hamstring strain for Adelaide defender Isaac Cumming.

The 26-year-old pulled up at training at Adelaide Oval on Monday and despite efforts to continue, left the track early.

Crows General Manager High Performance Ian McKeown said Cumming would likely miss the next one-to-two weeks.

Young forward Tyler Walsh also underwent scans on Tuesday for a hamstring strain sustained on Monday night.

“Tyler’s hamstring injury does appear to be more severe than Isaac’s,” McKeown said.

“We’re expecting he’ll be unavailable for the next three-to-four weeks.”
