The forward missed the final 47 games last season and had arthroscopic surgery in February to remove fragments from his left knee. The Devils play preseason games against the New York Rangers on Friday and the New York Islanders on Saturday.
"I've felt good," Hall said. "I think there's maybe a couple things I want to feel a little bit better on, but for the most part I can't complain. My energy has felt good every day after [practice], and this is a pretty hard training camp, so you're putting yourself through a lot and the knee has held up pretty well so far.
"I'm just going to keep pushing it, and when I talk to the medical staff, we'll see what games they want to put me in, if any, but things are trending pretty well."
Hall had 37 points (11 goals, 26 assists) in 33 games last season. In 2017-18, he won the Hart Trophy voted as the most valuable player in the NHL after scoring an NHL career-high 93 points (39 goals, 54 assists) in 76 games.
"We're going to talk about [Hall possibly playing a game this weekend] on Thursday, but we had talked about either him playing two or three games," Devils coach John Hynes said. "He had a pretty good practice [Wednesday] so we'll see how he is Thursday. There's a chance he will play but no guarantee."
