The expected return of AFL soccer star Alex Johnson was interrupted on Sunday after the Sydney Swans defender was injured at the end of the first quarter.

Nicknamed the most persistent soccer player, the clash against Melbourne at the Melbourne Cricket Ground was Johnson's second game after a 2136-day hiatus.

The 26-year-old was helped to take off in the first quarter of the game, believing that he had injured his "right" right knee.

The defender went to change direction while chasing Melbourne player Jesse Hogan near the border line.

Johnson's knee seemed to bend under him when he stumbled and landed awkwardly.

His teammate Nick Smith went to see him before the coaches reached him.

Johnson has not played AFL football since the grand final of 2012, which means the Swan have played 143 games without him.

He has fought through 12 knee surgeries, and could be looking at another.

Swans general manager Tom Harley feared the worst, saying it could be an ACL injury.

"Which is disappointing for everyone, but he more than anyone knows we have a job to do now," he said.

Entering the locker room for part time, his defense colleague Dane Rampe said: "We'll worry about that later."

Entering the halftime, the Swans lead by 14.
