The England international lock has overcome a back injury to take his place in the side for the first time since the Premiership Final in May.
Deacon’s return is timely following long-term injuries to Geoff Parling (knee) and Ben Pienaar (Achilles).
Lee Robinson makes his first Aviva Premiership start for the club on the wing as Scott Hamilton moves to full-back in the absence of Geordan Murphy who is on international duty with Ireland.
Jordan Crane, who led out the team in the LV= Cup tie against Harlequins three weeks ago, will captain the side in a league fixture for the first time.
