Trainer Desleigh Forster is searching for a new rider for veteran Someday in the Sunshine Coast Cup.

Someday was ridden by Melbourne's Michael Walker when he won the $300,000 Listed Bernborough Handicap on December 30.

Walker is unavailable on Saturday and Forster has been chasing another rider for the $100,000 1400m-race.

"I was planning on getting Michael Cahill but he is riding Torgersen for Chris Waller. I have a few days to chase a rider and there are a few other options," Forster said.

The trainer has been working Someday at the beach and the nine-year-old has done well since his win.

She also hopes to have promising Malvern Estate in a restricted class race at the Sunshine Coast.

"He was one of several horses who missed a run in the Magic Millions Cup after a wash-out of another meeting left them ineligible," she said.

Horses had to have a set number of races at provincial tracks to qualify to run in the Cup and when the Beaudesert meeting was washed out it left several horses one run short.

Forster came away happy from the Magic Millions sale after successfully bidding on a full brother to stakes winner Too Good To Refuse who is by Rothesay out of Alyssa Jane.
