He sparked discussion during his round after removing his shoes on the 10th green following a birdie putt.
The PGA Tour released a statement: "Lucas had been asked to be mindful of his spike marks on the green and was trying to be lighthearted."
Glover addressed complaints about his metal spikes: "There were some complaints about my metal spikes marking up the greens from some guys behind me.
Rules official notified me. Was just being silly, there's no way to not mark up soft, damp bent greens.
Oh, and we can tap down spike marks now."
