From Trail Blazers PR:
X-rays of LaMarcus Aldridge's left hand are negative. He will be further evaluated on Tuesday.

You can see video of the injury play here.
Update: Unsurprisingly, Aldridge will not travel to Phoenix for Wednesday's game versus the Suns. Mike Richman of OregonLive has the report. Jabari Young with the Tweet:
