The former Watford star lobbed Dons goalkeeper Alex Bass, and then bundled in, with 15 minutes to go cancelling out James Ball's first-half strike.
Deeney's arrival added to the goal threat for a side already boasting fellow summer addition Matty Taylor as well as Matty Stevens, who scored 23 goals when Rovers were promoted from League Two in 2021-22.
Deeney may face competition from teammate Ty Omotovo who toye, was in close attendance, to claim his goal while Stevens spurned several opportunities at Plough Lane.
But Horseman feels it will not be long until his illustrious strikers are regularly finding the net for a side who have scored just three times in their opening five matches.
"Troy lifted it and he says he bundled it in," Horseman said.
"I will have to check the video but him and Ty will have a conversation about that one.
"That is the most minutes that Matty Taylor has played so far, since I have come here, and he will only be stronger for it.
