SCRUM half Danny Richardson has been recalled to Saints' squad for Thursday's trip to Wakefield.

The decision ties in with the changes coach Justin Holbrook suggested yesterday when he said he would change things after the the defeat by Wigan.

Theo Fages and Matty Smith are also in the 19, as is Ryan Morgan, who picked up a head knock against Wigan.

Saints are currently three points behind Wakefield with three Super 8s games to play - so a victory is essential if they are to stay in contention for a top-four spot.

Matty Lees is included in the 19, while Kyle Amor drops out.
