The Panthers wanted to extend Stewart's contract earlier this offseason, but were unable get a deal done for the durable fourth-year back who's entering the final year of his contract.
"I definitely hope things work out," Stewart told The Associated Press. "I want to be back. I think we have a lot of weapons on offense and we can be a dangerous team."
Stewart carried the ball 142 times last season, the fewest in career, for 761 yards and four touchdowns on the ground. His carries diminished in part to the running of quarterback Cam Newton.
