Saints have opted to make one change for Saturday’s clash with Worcester Warriors at Franklin’s Gardens (kick-off 3pm).
The alteration comes in the second row, where Michael Paterson replaces Api Ratuniyarawa, who is on the bench.
Saints have tinkered with their replacements, with Sam Dickinson back on the bench in place of Ben Nutley and James Wilson replacing Rory Hutchinson.
Teimana Harrison again starts at No.8 after his release by England earlier in the week.
Saints were beaten 46-31 at Newcastle Falcons last Sunday, slipping down to eighth in the Aviva Premiership standings.
And they desperately need to produce a response against the Warriors to extend a four-game Gardens winning streak.
Meanwhile, Worcester are hungry for points in their battle against relegation.
They name Phil Dowson in their side as he starts at six.
Dowson, who left Saints for Worcester in 2015, will be hanging up his boots this summer to take a job as assistant coach at the Gardens.
