Rob Gronkowski isn't sure if he will be ready for the start of the 2014 season as he recovers from a torn ACL.

"Oh man, that's too far away. I'm just improving every day right now," Gronkowski said Tuesday on the "Hill-Man Show" on WAAF-FM. "I'm working hard every day to put myself in the best situation so that I'm ready."

Gronkowski had surgery on Jan. 9, with the procedure performed by Dr. James Andrews.
