The off contract midfielder has won a contract after successful trials before the UK's coronavirus lockdown.
Lewis told Nettavisen, "They spotted me playing here at home in Tromsø during the Itromsø Cup this winter.
"I trained with the A team. It was huge. That's the only thing I can say now.
"There is a lot of reports, but just wait and see. I think you will see something coming in a few days or a week."
Lewis was with Norwegian Second Division Fram Larvik this season.
