Hastings had returned home from England last week with a sore left foot after suffering an injury during Worcestershire's four-day County match against Sussex.
"I had a bit of pain in my left ankle for a little while and I thought I should get it checked out," Hastings was quoted as saying by RSN Breakfast Club.

Hastings said his injury could have been a lot worse.
