Bad news for the Ravens. Running back Kenneth Dixon suffered a tear in his meniscus, a source tells Ian Rapoport of NFL.com (on Twitter). He’ll undergo surgery with the hope that the meniscus only needs to be trimmed. After the operation, we should know more about Dixon’s condition and timetable for a return.

Dixon was already slated to miss the first four games of the season due to a PED suspension. Now, he’ll have to miss valuable camp time that he was hoping to use to separate himself from some of the other running backs on the roster.
Dixon, a fourth-round pick in the 2016 draft, was part of a committee backfield employed by the Ravens last season. He was on the short end of the stick, however, as he finished out with only 88 carries. The 23-year-old put up a solid 4.3 yards per carry average on those limited attempts and also added 30 receptions.
Terrance West, free agent addition Danny Woodhead, and Buck Allen are expected to be the top backs for Baltimore to start the year. Lorenzo Taliaferro profiles as the RB4 to begin the season while the newly-signed Bobby Rainey will try to push for a roster spot.
