Both forwards leaving the field in the fourth quarter but have been cleared of any injury setbacks by club doctors.
Schulz suffered a knocked his head on the playing surface while attempting to mark late in the game, but was able to return to complete the match.
"Jay had a minor knock to the head and we took him off to make an assessment, but he was medically determined not to be concussed," club doctor Mark Fisher told portadelaidefc.com.au after the game.
"Therefore he was fit to return and finish the match and will be fine to play Fremantle."
Westhoff knocked a knee while attempting to execute a tackle late in the game, but no injury was sustained and his non-return to play was merely precautionary.
Matt White was substituted from the game, but will also be fine to play the Dockers.
With Campbell Heath cleared from his knee rehabilitation earlier in the week, it means Port Adelaide's injury list will sit at just three players - all in long-term recovery - on Monday, barring any issues to come from the club's SANFL game against Glenelg on Saturday.
