Lupul left Thursday night's game against the Philadelphia Flyers after being sandwiched by Adam Hall and Jay Rosehill in the first period. The Maple Leafs forward appeared dazed after the incident. He would not return to the game.
The extent of his night spanned 1:40 of ice-time over three shifts.
Lupul was unable to participate in practice on Friday. Carlyle stated that Lupul went for an evaluation earlier in the morning and his ability to travel with the team to New Jersey has yet to be decided. He refused to label the injury a concussion.
Lupul has experienced a bittersweet 2013.
After signing a five-year, $26.25 million extension on Jan. 20, he fractured his forearm, which forced him to miss 25 games. Lupul was on fire in the two games he played after the injury, registering three goals and an assist, before being suspended two games. Following his suspension, he resumed his productive ways, registering a goal in every game he played.
While he was unable to score a goal in his abbreviated appearance on Thursday night, he still managed to register an assist on the Maple Leafs opening goal.
In total, Lupul has registered eight goals and six assists for 14 points in the six games and 100 seconds he has played since returning from injury.
