The Wests Tigers led the undefeated Storm side with mid way through the second half, with late tries to Melbourne seeing the side return without the two points.
Potter said that Benji Marshall is hopeful of playing, but will await the results of a scan on his injured toe tomorrow.
We are currently in the process of checking the extent of injuries to Benji Marshall and Liam Fulton, Potter said.
Fulton will come back into the side and will be monitored throughout the week.
We are also waiting on Bodene (Thompson) and Adam (Blair) who have been cited at the judiciary. It doesnt appear to be much in it though.
Potter said he was impressed with the sides improvement in last nights 26-12 loss to Melbourne.
I think we are getting closer to where we want to be, Potter said.
We have shown a lot of improvement but we are still a little way off.
We need to be able to mix it with those top sides every week and we are building towards that.
The much-anticipated Heritage Round clash with the Dragons at the Sydney Cricket Ground will kick-off at 3pm this Sunday April 14.
