The 27-year-old left wing can become an unrestricted free agent July 1, 2020, but could sign an extension of up to eight years with the Devils before then.
Part of the reasoning behind the Devils' aggressive offseason, including signing forward Wayne Simmonds and trading for defenseman P.K. Subban and forward Nikita Gusev, was to entice Hall to remain with them beyond this season. However, it's unlikely he will get a contract extension prior to the start of the regular season.
Hall has something to prove after missing the final 47 games last season and having arthroscopic knee surgery in February. He had 37 points (11 goals, 26 assists) in 33 games but hasn't played an NHL game since Dec. 23, 2018.
He won the Hart Trophy voted as the NHL most valuable player after scoring an NHL career-high 93 points (39 goals, 54 assists) in 76 games in 2017-18.
