Two of Saratoga's biggest stars from last summer are working their way back to the races after some setbacks.

Travers winner Summer Bird, who also captured the Belmont and Jockey Club Gold Cup in his championship campaign last year, has been galloping regularly at Delaware Park, but missed going to the track this week because of a temperature.

The 4-year-old, who hasn't run since finishing a credible fourth behind Zenyatta in the Breeders' Cup Classic, is working his way back from a condylar fracture suffered while training for the Japan Cup Dirt late last November. Buring the interim, he was transferred from trainer Tim Ice to Tim Ritchey, who conditioned 2005 champion Afleet Alex.

Ritchey is hoping to breeze Summer Bird this month and have him racing in June. A return to Saratoga is on the slate for the strapping chestnut, as Ritchey mentioned the Whitney and the Woodward as summer goals.

Meanwhile, Careless Jewel, winner of the Alabama, will miss the Shuvee at Belmont this weekend after developing some heat in a leg. It's the second setback of the year for the 4-year-old filly, who missed a planned start in the La Troienne on April 30 with a quarter crack. No plans have been made for her next start, which will be her season debut.

Careless Jewel won five of seven starts last year but hasn't started since fading after setting the pace in the Breeders' Cup Ladies Classic last fall.
