Jagr left Tuesday's game against the Penguins in the second period with an apparent head injury and will not return, Tom Gulitti of the Bergen Record reports. Jagr was one of three Devils forwards (Patrik Elias, Stephen Gionta) to leave the game with an injury, with his looking like the most serious of the three. The injury occurred when he was struck in the head and into the end boards by the Penguins' Robert Bortuzzo, who could face a suspension for the hit. Jagr had previously dealt with a nasty cold in the morning, so the injury only further complicates matters. Consider him questionable for Thursday's game against the Maple Leafs until the team updates his condition.
