MATT WHITE will have scans on Monday to determine the extent of a hamstring injury suffered in Friday night's loss to Geelong.
White was aided from the ground in the second quarter and immediately put in the red substitute vest with Aaron Young replacing him.
Power high performance manager Darren Burgess says the outcome of the scans won't be known until Tuesday.
"Whitey thinks its a decent one, but it's hard to know until we've scanned and assessed it," Burgess said.
"We won't know until Tuesday when the results come in, from there we'll have a clear idea of how long [he'll be sidelined]."
No other injuries were reported from the Power's 23-point loss to Geelong.
