With one preseason game under their belt and heading into a day off before their second, the Ravens had a relatively light, abbreviated practice on Thursday.

Much of the padless defense operated at half-speed, inflating the offensive output. And there appeared to be an extra sense of levity to individual drills.

Quarterback Lamar Jackson got off to a hot start in 11-on-11 action, completing his first four passes. Three went to Tylan Wallace for medium-distance pickups. The other was a post route to Zay Flowers, who burst off the right side and beat cornerback Marlon Humphrey over the middle for a touchdown.

The offense cooled off in the middle portion under Jackson’s control.

He looked for Isaiah Likely in the end zone but found the outstretched hands of linebacker Deion Jennings, who dropped the potential interception. Linebacker Yvandy Rigby bobbled a throw from Jackson before hauling in his pick, also in the end zone, on a pass intended for Anthony Miller.

Undrafted rookie Bump Cooper Jr. later forced an incompletion draped over Malik Cunningham. Cooper nearly picked off backup Josh Johnson later in practice on a ball he should have caught.

Ignoring a few would-be sacks and one pass interference call, Jackson wrapped on a high note with a string of red zone completions. That included a pair of touchdowns to Likely and Flowers to end practice.

The Ravens host the Atlanta Falcons at noon Saturday, and Jackson isn’t going to play. Next week, Baltimore travels to Green Bay for some joint practices before they face the Packers in the third preseason game, the final tuneup before the regular-season opener Sept. 5 against the Chiefs in Kansas City.

Wiggins, Mullen return

Rookie cornerback Nate Wiggins returned to practice Thursday after suffering a shoulder injury during last week’s preseason game against the Philadelphia Eagles. He was an immediate bright spot, breaking up three passes during the game’s opening drive, but exited in the third quarter.

The first-round draft pick sprinted alone with a trainer Wednesday but did not participate with the team. He returned a day later wearing a padded brace on his injured shoulder.

Wiggins did participate in some 11-on-11 action Thursday. On a string of plays during his first series, his side of the field was rather quiet. He later surrendered a pair of catches.

More positive injury updates: Cornerback Trayvon Mullen was back taking full-team reps for the first time since returning from his shoulder injury earlier in camp.

Two players on the fringe impress

Undrafted rooked tight end Qadir Ismail had perhaps the play of the day, hauling in a pass from Johnson with a full-body extension in the back right corner of the end zone. Safety Ar’Darius Washington — who has had an impressive camp — was a step behind in coverage.

Miller also continues to show good juice and could challenge for a back-end spot on the roster if fellow receiver Devontez Walker, who was absent Thursday and has been dealing with a rib issue, ends up on injured reserve to start the season.

Tampa’s early exit (again)

T.J. Tampa made his training camp debut Monday after recovering from a sports hernia injury that previously put the cornerback to the physically unable to perform list. Baltimore’s late-fourth-round pick, who many considered to be a steal at that point in the draft, has been ramping up each day this week, having gone through individual drills before heading inside at the start of 11-on-11 action.
