This news was reported by Jonas Siegel of The Athletic, who noted that Tavares was limping and favouring his right leg.
This news comes less than 24 hours after a horrible loss to the Dallas Stars where the Maple Leafs were completely catatonic for most of the game.
Tavares is in the midst of a slump right now and there is no doubt that this injury could very well set him back for quite some time.
The Leafs as a whole are currently on a three-game losing streak that has come at a huge cost to the team's lead in the Atlantic Division standings.
At the time of writing this, the Maple Leafs are now hanging on by a thread to their lead, with the Florida Panthers just one point behind.
On Thursday night, the Leafs will be back in action against the New Jersey Devils and as it stands, there is no telling if Tavares will be able to suit up.
There are still plenty of unknown as it pertains to what happened to Tavares at practice today and we're sure an update is coming soon.
Now that we are in the second half of the season, the health of the team's players is extremely important.
The Leafs cannot afford to get any more injuries especially when their offensive has struggled to get anything going.
Hopefully, the Leafs get good news, otherwise, things could get ugly for the team.
