Puissance De Lune's tendon injury is far from healed but his trainer Darren Weir remains optimistic he can make a comeback in the spring.

The high-profile galloper pulled up from his unplaced Cox Plate run last spring with the injury which put his racing future in doubt.

Weir said Puissance De Lune would have a preparation aimed at returning to racing in the spring with owner Gerry Ryan also keen to give the horse the opportunity.

The six-year-old had scans last week to check on the progress of the injury.

"One lesion is healing up really well and the other lesion is going a little slower than expected," Weir said.

"We've got heaps of time so he's fine.

"Gerry is keen to race again next spring. Obviously when we bring him into work and if things aren't going the right way, well he'll go to a stud career then."

Weir said they were monitoring Puissance De Lune's progress closely.

"The leg needs a lot more time than what it's had yet, but we're just scanning it more regularly than what you would a normal horse. Just to see the progress," Weir said.

"He's at the stables at the moment. The vets are looking again next week and then he'll go back to Gerry's farm for a bit of a break in the paddock hopefully and then come in and do a big rehab program."

Puissance De Lune emerged as a boom horse in Australian racing in the spring of 2012 with emphatic wins in the Bendigo Cup and Queen Elizabeth Stakes at Flemington.

The long-time favourite for last year's Melbourne Cup, Puissance De Lune did not make to the race.

He won the Group Two Peter Lawrence Stakes first-up last preparation but was narrowly denied on two occasions in Group Ones with seconds in the Makybe Diva Stakes and Turnbull Stakes.
