The first week of training camp inevitably leads to players getting banged up and injured across the league, and the Baltimore Ravens are not exempt. Afterwards, head coach John Harbaugh gave updates on all of them, with the most notable and significant being about two-time Pro Bowl cornerback Jaire Alexander, who was absent from the practice field for the first time. “He had a little swelling and we wanted to drain his knee today,” Harbaugh said. Given Alexander’s checkered injury history, hearing that he is already having to miss any amount of time might spook some fans and skeptical optimists of this year’s team.
