Baltimore Ravens running back Justin Forsett suffered a broken right arm against the St. Louis Rams Sunday, according to tweet posted by NFL reporter Ian Rapoport which can be seen below.

The Ravens running back suffered the injury when he was tackled by St. Louis Rams defensive end Aaron Donald. Forsett is out for the rest of the game, and head coach John Harbaugh will look to running back Javorius Allen to step up. Allen only has 42 carries for 182 yards, and the Ravens rookie running back will get plenty of carries down the stretch of this season, with Forsett likely out for some time.

It has been a difficult year for Baltimore fans, as they sit at 2-7 prior to Sunday's game and are currently a half a game out of last place in the AFC North. The Ravens have already lost star wide receiver Steve Smith Sr. with a torn Achilles, and Baltimore is clearly already in rebuilding mode for next season.

The Ravens already have a their franchise quarterback in Joe Flacco, but they are struggling to surround him with talent. With Forsett likely out multiple games, the Ravens will take a deep look at Allen and see if their fourth round pick can turn into a legitimate NFL running back.

Forsett wasn't the only major running back injured on Sunday, as Atlanta Falcons running back Devonta Freeman suffered a concussion against the Colts, according to NFL reporter Marc Sessler. Freeman has been ruled out, and the Falcons will look to running back Tevin Coleman and Terron Ward to handle the carries for Atlanta's offense. Coleman was the Falcons third round pick in the 2015 NFL draft, and expect him to see plenty of carries with Freeman on the sideline.
