FORMER Saints scrum half Matty Smith has made a surprise move to rivals Warrington.

The half back, who played at Saints in spells between 2006 and 2010, rejoined his hometown club from Wigan in 2017.

However, he lost his place to Danny Richardson in the last year of his contract and moved to Catalans at the start of the season.

He is expected to play against Saints in the Super League clash on Thursday.

Warrington have had half back concerns this year - losing Kevin Brown in the off season and then saw Blake Austin limp off on Saturday in France.

No update on the latter has been given yet.
