Boykin departed Monday's practice early due to a hamstring injury, Jamison Hensley of ESPN.com reports.
Coach John Harbaugh said "we'll have to see" when asked about the severity of Boykin's injury. The 2019 third-round pick already was off to a slow start at training camp, in addition to facing increased competition, so he can ill afford to miss much time. Marquise Brown (hamstring) and Rashod Bateman (undisclosed) are also dealing with injuries, and quarterback Lamar Jackson (COVID-19 list) won't be back on the field until Friday, at the earliest.
