Regular jockey Kathy O'Hara will climb aboard for the Become An ATC Sponsor Handicap (1100m) in what will double as a test for the horse's future prospects.
"He was put in the paddock and he's freshened up now, so I hope that he's back to what he was at Scone," Coyle said.
"He's still got to prove what sort of quality horse he is and that's going to be a matter of going back to the races and winning races."
Coyle said his decision not to run Sweet Serendipity in a barrier trial this time was deliberate.
Coyle will be hoping Sweet Serendipity and O'Hara can follow up Saturday's Randwick win of stablemate Flight Academy.
If not, the trainer-jockey combination will have other Canterbury chances in Takewing (Australian Turf Club Maiden Hcp) and Smart Moochi (Canterbury Park Hcp).
