Drouin, ranked No. 1 on NHL.com's list of the Top 60 prospects in the League, is officially listed as day-to-day.
"This is not a long-term thing,"’ coach Jon Cooper told The Tampa Tribune. "For us, his training camp started (with the prospect team) on Sept. 11. He played three games in the rookie tournament, and he’s grinded it out. He got nicked up a little bit, and the one thing is that, this is by no means serious. We expect he’ll be back next week at some point. ... It was a freak thing, so there is no alarm."
