I wonder if it was OK. All the common lizards I've seen have been very quick and often too fast to catch, never mind hold on an open palm
It appeared to be ok and did move albeit slowly. We figured it was a newt as it wasn't far from a know newt & frog habitat.
You can see a lump at the top of the front left leg and I have just looked closer (because you said you wondered if it was ok) and can see quite a bad diagonal cut across the 'knee' of the rear right leg, also the last third of the tail looks black, didn't notice that at the time but then I didn't have my specs on at the time. There appears to be some scale damage (right side halfway along back).
I can see the scales now and the 5 toes on the front legs.
