Ivo Karlovic is recovering in a Miami hospital after being diagnosed with viral meningitis. It's good to see that Dr. Ivo's sense of humor is still going strong.

"What i learned today: dilaudid is 5 times stronger than morphine. And its [sic] gooooood," Karlovic tweeted.

Karlovic followed that tweet by adding, "Thanks everybody for prayers and good wishes. It really helped. You the bestest."

The big-serving 34-year-old requested rankings points as a get-well gift, as the ATP's Greg Sharko tweeted.
