Etuhu will feature for Cardiff in today's Premiership playoff at Wembley against Blackpool.
He told City's website: "Who knows what may happen at the end of the season? There may be the option of spending further time on loan at Cardiff but we'll have to wait and see.
"All I'm thinking about at the moment is doing my part to help Cardiff reach the Premier League on Saturday afternoon. If we play the way I know we can then I hope we can get that result."
