Training camp is off to a incredibly rough start in Baltimore.

Becoming the latest Ravens player lost to injury within the first few days of the summer practice schedule, fourth-round rookie guard Nico Siragusa suffered tears to the ACL, MCL, and PCL in his knee, NFL Network’s Ian Rapoport reports, citing sources.

Siragusa’s injury, which almost certainly puts him out for the entire season, comes with running back Kenneth Dixon and tight end Crockett Gillmore already lost for the year and quarterback Joe Flacco working through a back issue.

A three-year starter at San Diego State, Siragusa was in line to challenge for a first-team role as a rookie.

He’s instead forced into a major rehab just days into his first training camp, and the Ravens are now forced to test the depth on what was already a thin offensive line.
