Tampa Bay Lightning forward Brandon Hagel exits after hit - ESPN

Tampa Bay Lightning forward Brandon Hagel left Game 4 of their series against the Florida Panthers on Monday night after a high hit from defenseman Aaron Ekblad that wasn't penalized.

With less than 9 minutes left in the second period, Hagel played the puck out of the Tampa Bay zone near the boards. Ekblad skated in on him and delivered a hit with his right forearm that made contact with Hagel's head, shoving him down in the process.

The back of Hagel's head bounced off the ice. He was pulled from the game for concussions concerns. Ekblad did not receive a penalty on the play.

The Lightning trailed the Panthers 1-0 at the time of the hit, but Mitchell Chaffee and Erik Cernak scored two goals in 11 seconds after Hagel left the game to give Tampa Bay the lead.

When the teams returned for the third period, Hagel was not with the Lightning, and the team's communications staff told ESPN's Emily Kaplan that he was still being evaluated.

Game 4 saw Hagel return to the Tampa Bay lineup after he served a one-game suspension for interference on Florida captain Aleksander Barkov in Game 2. The NHL ruled the Barkov wasn't eligible to be hit and that Hagel made head contact with him. It was the first suspension of this career.

Hagel was one of the best two-way wingers in the league this season, with 35 goals and 55 assists in 82 games for the Lightning.

Florida leads the series, 2-1.
