I thought that too at the beginning when he wasn't seen for about 15 minutes, but I realize that it was probably just to throw that curveball with the reveal he had been poisoned by the leech venom, a "what happened to the Doctor?" setup. I believe he's still had enough involvement in that episode to constitute a normal-size role, unless stated otherwise directly from the production crew.
