Tiger Woods and Rory McIlroy are two of the biggest names in the game of golf today. Unfortunately, only one of them -- McIlroy -- is currently playing competitively on tour. Woods, on the other hand, is recovering from multiple back surgeries and isn't sure when he'll return to golf.

There were a couple of reports that surfaced on Monday saying there's no imminent return for the 14-time major champion, but they were quickly refuted by his agent, Mark Steinberg. He called them "ridiculous and absolutely false," but there were still questions about Woods' health.

On Wednesday morning, Woods attempted to silence the doubters with a response of his own, posting this video on Twitter with the caption "progressing nicely."

McIlroy, who was criticized by Golf Channel's Brandel Chamblee last week for essentially working out too much like Woods, responded to Tiger's video with an absolutely perfect tweet. Well played, Rory.

While you're on your feet, do a few calf raises would ya? https://t.co/MXLTjcHwC4

McIlroy's response was both a playful jab at his friend Tiger, and a shot at the critics -- mainly Chamblee -- for his intensive workout plan. Surely, this got a good laugh from Woods, himself.
