The 26-year old, who is usually deployed as a left-sided midfielder, was thrown in at left-back as the Galaxyâ€™s USL PRO side defeated Charlotte Eagles 2-1.
"He did okay. We want to try him at that position as well to help give us a little cover," said Arena.
Rogers played at left-back for the USA team at the Beijing Olympics so said it was not too unusual for him to slot back there with Curt Onalfoâ€™s Galaxy II.
â€śIt was different. I played there once in the Olympics and [former U.S. National Team head coach Bob Bradley] used to put me there in training,â€ť Rogers told the clubâ€™s official website.
â€śWith the way things are with injuries to the first team. They thought it would be good to give me a look.
â€śIt was good to get tested and I thought that we did a good job defending,â€ť added Rogers. â€śIt was just good to get a rep in and play back there again.â€ť
Rogers, who has been battling injury in the early stages of the MLS season, joined LA in May last year but has made just 16 appearances for the senior side.
