You can see Jose Tyler's bandaged hand starting with the very first shot he appears in on the bridge. But here's a shot as the landing party is beaming down for the first time (certainly well before the laser cannon is used on the rocky knoll). You can see Tyler (way over at screen left) has his right hand wrapped with a flesh-colored ACE bandage, and the Geologist way over at screen right has a white bandage on the left side of his neck.
So you can.
I must be getting old, 40 this year.
