Baltimore Ravens' John Harbaugh frustrated with Breshad Perriman injury absence

Baltimore Ravens head coach John Harbaugh has admitted that he is frustrated by the absence of Breshad Perriman from his side's training camp due to injury.

The Ravens selected the wide receiver in the first round of the 2015 Draft, but the 21-year-old suffered a knee injury in his first practice session of camp three weeks ago and has been unable to return.

"I hate that he's not out here," Harbaugh told reporters. "I have a knot in the pit of my stomach in some ways about it.

"In other ways, I know it's all out of our control, and I'll put it in God's hands and let him take care of it. To me, that's the best strategy, right there."

The Ravens open their season against the Denver Broncos on September 13.
