Lynch, 28, rushed for 1,306 yards and a league-leading 13 touchdowns last season. He rushed for 318 yards and a pair of scores in the playoffs as the Seahawks reached the Super Bowl. He battled a back injury during the second half of the season and has reportedly considered retiring.
Schneider said Seattle wants Lynch to return next season, and that the team would restructure his contract that calls for him to make $5 million.
"Whether or not he wants to play next year, I can't answer that," Schneider said. "I don't know if he knows at this juncture."
"I think he needs to find out where he's at and if he wants to -- It's hard for these guys," Schneider said. "It's a long season. We've played lot of football these last two years."
NFL.com's Ian Rapoport reported earlier this month that the Seahawks were prepared to offer Lynch a "huge" contract extension.
Schneider also discussed quarterback Russell Wilson's upcoming contract negotiations, saying he will sign a deal that allows the team to continue competing for championships.
"I think Russell Wilson wants to win championships," Schneider said. "We talk about being a consistent championship caliber football team and that means thinking outside the box a lot of times. We will do that with Russell. Russell knows there are certain dominoes that have to fall in line."
Last month, it was reported that the Seahawks planned to make Wilson the highest-paid quarterback in the league. Wilson has said that he wants to play his entire career in Seattle.
