Myles Garrett, Jabrill Peppers and David Njoku, the Browns' three first-round picks in the 2017 NFL Draft, are back in Berea for rookie minicamp.
The trio is among 21 new faces who will report to the team's facility on Thursday afternoon for their first pair of NFL practices, which are set for Friday, Saturday and Sunday. A number of tryout players are also reporting.
This will be the first chance Jackson, executive vice president of football operations Sashi Brown, vice president of player personnel Andrew Berry and others get to officially look at the newest members of a new-look roster.
The Browns drafted 10 players last month, including Garrett, the former Texas A&M defensive end and No. 1 overall pick. They took Peppers, the dynamic Michigan safety/linebacker/kick returner, at No. 25 and Njoku, the former Miami tight end, at No. 29.
They'll also welcome former Notre Dame quarterback DeShone Kizer, whom the Browns scooped up in the second round. This weekend will give Jackson and quarterbacks coach David Lee their first official look at Kizer, a two-year starter and Toledo native who will compete alongside Cody Kessler, Brock Osweiler and Kevin Hogan.
The Browns agreed to terms with 11 undrafted free agents last week, including four defensive backs and three linebackers.
Fifty-seven members of Cleveland's 90-man roster are in either their first or second NFL season. It's part of a plan, the Browns have said, to create and develop a "core nucleus of young talent."
"We like guys that are arrow up. The longer the arrow is up, the better for us," Brown said last month in a post-draft press conference. "We're trying to build a group that is going to be together for a long time. For us, that is the really great thing about the last draft class, this draft class and the next one."
The Browns, who are trying to bounce back from a 1-15 season in 2016, own 12 draft picks in 2018, including five in the first two rounds.
Cleveland's veterans will finish Week 4 of offseason workouts Thursday. The rookies will join their older counterparts for OTAs, which begin May 23. Mandatory veteran minicamp starts June 13.
