(The Sports Xchange) - The Baltimore Ravens lost quarterback Joe Flacco to a concussion and still managed to snap the Miami Dolphins' three-game winning streak with a dominant 40-0 victory on Thursday.
Flacco was injured on a hard hit by Miami linebacker Kiko Alonso after a 9-yard run late in the second quarter. Alonso was penalized for a personal foul and had his helmet knocked off by Baltimore center Ryan Jensen in retaliation.
After the play, Ravens coach John Harbaugh also got into a verbal altercation with Alonso and had to be held back by an official.
Backup Ryan Mallett entered and threw a 2-yard touchdown pass to Benjamin Watson, who beat Alonso on the play, to give Baltimore (4-4) a commanding 20-0 lead just before halftime.
Ravens running back Alex Collins had a career-high 113 yards on 18 carries against a Dolphins defense that entered the game ranked fifth against the run.
Baltimore linebacker C.J. Mosley returned an interception 63 yards for a touchdown for a 26-0 lead with 14:16 left in the game.
Frustration boiled over for the Dolphins (4-3) with 6:59 remaining when defensive end William Hayes was flagged for another unnecessary roughness penalty. Miami defensive tackle Ndamukong Suh also appeared to grab Mallett by the neck.
Ravens running back Javorius "Buck" Allen fumbled on the next play, but receiver Chris Moore recovered in the end zone and Baltimore led 33-0.
Jimmy Smith capped a stellar day by the Baltimore defense with a 50-yard interception return for a touchdown that rounded out the scoring.
It was the largest shutout margin in Ravens history.
Dolphins quarterback Matt Moore, who was making his first start of the season for the injured Jay Cutler, struggled much of the night, going 25 for 44 for 176 yards with two interceptions. He had a 47.1 passer rating.
Flacco was 10 of 15 for 101 yards and a touchdown before exiting. Mallett completed 3 of 7 passes for 20 yards and a score.
Baltimore wound up with a 295-196 edge in total yards.
The Ravens took a 7-0 lead on a 35-yard touchdown pass from Flacco to Jeremy Maclin with 8:19 left in the opening quarter. Miami appeared to be caught off-guard with Baltimore's no-huddle and was flagged for 12 players on the field.
Justin Tucker boosted the lead early in the second quarter with a pair of field goals from 55 and 48 yards. Mallett's touchdown pass to Watson with 1:56 remaining gave Baltimore a 20-0 cushion at the break.
Miami running back Jay Ajayi had a 21-yard scamper on his first carry, and then managed just 3 total yards on his next nine attempts. Overall, the Dolphins were held to 87 yards in the first half.
