Flacco leaves game after vicious hit, irate John Harbaugh yells at Dolphins player

A fight almost broke out in Baltimore on Thursday after Ravens quarterback Joe Flacco took a brutal hit from Dolphins linebacker Kiko Alonso in a game the Ravens would win in a 40-0 rout.

The hit from Alonso ended Flacco's night and started total chaos on the field at M&T Bank Stadium. The craziness started after Flacco decided to scramble on a third-and-10 play from the Dolphins' 20-yard line. As Flacco was nearing the 11-yard line, he clearly gave himself up with a feet-first slide, and that's when Alonso came in with a blatantly illegal hit. 

Although Alonso was penalized for unnecessary roughness on the play, he wasn't ejected for the hit that knocked Flacco out of the game and put him into the concussion protocol. 

The hit was so big that Flacco signaled to the Ravens' sideline right away that he needed help. 

After Flacco went down, Ravens offensive lineman Ryan Jensen ran over to Alonso and knocked him straight to the ground. 

The push from Jensen knocked off Alonso's helmet and started a full-scale melee on the field. 

Ravens coach John Harbaugh was so irate after the play that he went after Alonso. 

However, Harbaugh wasn't able to get near him because he was held back by a ref. 

After Flacco left the game, Ryan Mallett came in and threw a 2-yard touchdown pass to Benjamin Watson that gave the Ravens a 20-0 lead. 

Flacco was 10 of 15 for 101 yards and a touchdown before he was placed in concussion protocol after the hit. The Ravens ruled him out for the rest of the game before the start of the second half.
