Undrafted tight end Qadir Ismail played an important role for the Ravens on their final day of training camp Tuesday before departing for Green Bay for their preseason finale: He covered up his purple No. 83 jersey with a yellow No. 87.

Coach John Harbaugh said Monday that the Ravens are shifting their focus to the Kansas City Chiefs, who host Baltimore on Sept. 5 in the NFL’s regular-season opener. So on Tuesday, Ismail roleplayed as Travis Kelce.

Kelce tormented the Ravens in the AFC championship game last season and has 33 catches for 435 yards and two touchdowns in five career regular-season matchups against Baltimore. Scout team quarterbacks Josh Johnson and Devin Leary peppered Ismail with targets in the flat, across the middle and up the seam to give Baltimore’s first-team defense a look at what they’ll potentially see from the star tight end in Week 1.

Ismail has had one of the most impressive camps of any Ravens pass catcher. Unfortunately for the son of former Ravens wide receiver and broadcaster Qadry Ismail, he plays the same position as Mark Andrews, Isaiah Likely and Charlie Kolar. And the Ravens likely won’t keep more than three tight ends.

Ismail could stick around on the Ravens’ practice squad. He’ll also have one more preseason game to perhaps show other teams he’s worth a roster spot. Until then, he’s helping the Ravens prepare for a familiar foe.

Adisa Isaac injured again

Isaac, a rookie edge rusher from Penn State whom the Ravens took in the third round, suffered another soft tissue injury, Harbaugh said Tuesday. This one is in the opposite leg from his previous hamstring injury, which kept him sidelined for most of the summer.

“It’s not going to keep him out like he was before,” Harbaugh said. “It’s just a matter of him working into football shape. He’ll have to work into that and I’m sure he will.”

The 22-year-old stood out in limited opportunities during Baltimore’s second preseason game Saturday before exiting early. Isaac didn’t practice Monday and worked on a backfield with trainers during Tuesday’s practice.

The Ravens’ edge rusher group is full of question marks and is now even more murky. The team is relying on Odafe Oweh and David Ojabo to take leaps in their fourth and third seasons, respectively, and continued production from 33-year-old Kyle Van Noy. Isaac could have helped supplement the loss of veteran Jadeveon Clowney, but it’s again unknown when the rookie will be ready to contribute.

Devontez Walker finally flashes

Walker has had a difficult training camp. He’s been uninvolved in most offensive sessions for weeks and hasn’t caught a ball in two preseason games as he works back from a rib injury. But Tuesday was one of his best days of the summer. The rookie fourth-round pick caught three passes from Johnson and Leary against the first-team defense, capped by a touchdown from about 50 yards out that he grabbed over safety Marcus Williams.

Walker was always likely to make the Ravens’ 53-man roster, even though they’ve been willing to cut Day 3 draft picks before and Walker’s struggled to stand out. He’s also a candidate to start the season on injured reserve if his rib injury proves too serious to play through.

Tuesday was a step in the right direction. Saturday will be another test for him to show he’s healthy.

Walker’s grabs were the lone highlights of an otherwise sloppy day from the offense. Lamar Jackson was out of sync with his receivers on multiple occasions. The star quarterback was intercepted by Ka’dar Hollman during goal line work on a ball intended for receiver Tylan Wallace, and several passes sailed incomplete because of miscommunication or incorrect routes.

Attendance report

Rookie running back Rasheen Ali returned in a limited capacity after missing Monday’s practice. He worked alongside Isaac with trainers on a side field for much of the afternoon.

Cornerback Marlon Humphrey and right tackle Patrick Mekari were both absent Tuesday, although Harbaugh said both are “fine.” Andrews missed practice again after a car accident last Wednesday in which the team said he did not suffer any apparent injuries.

Extra points

Anthony Miller was heavily involved in the offense, catching five passes from Jackson during team drills. Miller, who was signed two weeks ago and hasn’t played in a regular-season game since 2021, has impressed in his brief stay in Baltimore as he pushes for a roster spot.

Seventh-round rookie Nick Samac took reps as the starting center Tuesday for the second straight day. The Ravens are searching for a true backup at the position with Pro Bowl selection Tyler Linderbaum still out. Mekari and Ben Cleveland have spent time there.

The Ravens spent about 10 minutes Tuesday doing a field goal block exercise. Justin Tucker booted soccer balls while a rotation of defensive backs took turns exploding off the edge and diving to block Tucker’s kick. Only cornerbacks Nate Wiggins, Damarion “Pepe” Williams and Trayvon Mullen were successful.
