Cardinals' defensive end J.J. Watt tweets that he plans to play days after his "heart was shocked back into rhythm"

Arizona Cardinals defensive end J.J Watt tweeted Sunday that he would be playing despite that he "had my heart shocked back into rhythm" after it went into atrial fibrillation last week. 

Watt's tweet was posted just a few hours before the Arizona Cardinals are set to play against the Carolina Panthers.

"I was just told somebody leaked some personal information about me and it's going to be reported on today," Watts tweeted on Sunday. "I went into A-Fib on Wednesday, had my heart shocked back into rhythm on Thursday and I'm playing today. That's it."
