The GasGas rider was supposed to open the road having won Stage 6 but, according to event tracking, crashed in the liaison.
“The first reports are reassuring and speak of an injured left arm,” read an update on tracking.
“He received immediate assistance and has been taken to hospital.”
Sanders had been third overall at just 5:35s off the lead, held by GasGas team-mate Sam Sunderland, after also winning Stages 1A and 1B.
Price, who started the day 12th overall, was quickest to the first waypoint, 42km into the stage, and also quickest of those to have thus far reached the second waypoint, another 35km into the special.
Compatriot Molly Taylor is also still in the contest in SSV, for which the road opener is set to head off at 19:50 AEDT.
