Ferris said Hall's rehabilitation is going well and he remains on target to be ready for training camp in September.
The Devils (31-41-10) finished 29th in the NHL and missed the Stanley Cup Playoffs for the sixth time in seven seasons.
"We have the culture and character in our locker room but at this point in time, in my opinion, we lack some talent in positions," Hall said April 8. "Whether it's the players on our team getting better and improving, or from the outside. Certainly, when you finish 29th, you're lacking some skill and lacking some talent. The great part is we have a culture in our locker room that's fun to be around and conducive to success and hard-working people. Now it's about filling those gaps where we might have lacked this season.
"At this point I've enjoyed being a Devil and being around my teammates. The conversations about my future will happen."
Acquired in a trade from the Edmonton Oilers for defenseman Adam Larsson on June 29, 2016, Hall has one season remaining on the seven-year, $42 million contract he signed with the Oilers on Aug. 22, 2012.
The Devils have the No. 1 pick in the 2019 NHL Draft after winning the NHL Draft Lottery on April 9. Jack Hughes, who had 112 points (34 goals, 78 assists) in 50 games this season for USA Hockey's National Team Development Program under-18 team, is projected to be the No. 1 pick. He holds NTDP career records for assists (154) and points (228) in 110 games over two seasons.
Hall had an NHL career-high 93 points (39 goals, 54 assists) in 76 games in 2017-18, when he helped the Devils qualify for the playoffs for the first time in six seasons.
