The Ravens have placed cornerbacks Bilhal Kone and Robert Longerbeam on season-ending injured reserve, ending both their rookie years within a two-day span.

Kone, a sixth-round pick, was placed on IR on Saturday, two days after he suffered a knee injury early in a preseason win over the Indianapolis Colts.

Longerbeam, also a sixth-round pick, was designated Sunday as the Ravens cleared space on their 90-man roster for running back Myles Gaskin. Longerbeam hadn’t practiced since appearing to hurt his knee in a collision with rookie wide receiver LaJohntay Wester early in camp.

“That’s a long story,” coach John Harbaugh said of Longerbeam’s injury. He did not elaborate. “It’s just a long story.”

Both were contenders to make the Ravens’ initial 53-man roster. Their injuries should open the door further for cornerback Jalyn Armour-Davis, a camp standout, along with potential long shots like undrafted rookie cornerback Reuben Lowery.

The Ravens’ draft class has already been tripped up by injuries, with third-round pick Emery Jones Jr., an offensive lineman expected to contend for at least a backup role, sidelined by a shoulder injury. He did not participate in offseason workouts and has yet to be cleared to practice in camp.

“I would just say, man, there’s going to be some dark days going through rehab, but just keep pushing and keep fighting,” said wide receiver Rashod Bateman, who was limited to 18 games over his first two years in Baltimore because of injuries. “That’s the only thing that helped me. I didn’t know if I was going to have another contract or have another day, because when those things start happening in your career, opportunities start to dwindle. So you just never know how you’re going to end up, but just having always the mindset of: Keep going.”
