Clark, an in-form $369k DT ruck/forward, spent plenty of the second-half of the victory in Tasmania on the bench after experiencing some problems with his groin.
But Voss claimed Clark was only suffering from tightness rather than a muscle tear and he was on the bench as the Lions didn't want to risk injury.
"They are like gold to us at the moment,'' Voss said. "So we didn't want to put him out there unless we absolutely had too, it was more out of precaution.''
The Lions don't play again until June 27 against Melbourne at the GABBA.
One Brisbane player who might not be available for that game is Troy Selwood after dislocating a shoulder in the Hawthorn victory.
The Herald Sun has claimed the $244k midfielder will miss about a month due to the injury, but Voss downplayed such suggestions.
"Troy Selwood's popped his shoulder," Voss said. "Obviously we'll assess the damage. Hopefully he's right in a couple weeks. Sometimes they can just pop out and then come back in and they're OK."
