Updates on Kentucky Derby contenders and other news as the Run for the Roses is tomorrow.

Weather watch: Although the track on Oaks day was fast, the rain is expected to arrive in Louisville and continue through Derby weekend. The storms should roll into the area by 10 a.m. with heavy rain expected to last three or four hours; scattered storms and brisk wind could continue for most of the afternoon. With as much as two inches of rain expected, a flash flood warning is in effect in Louisville until Monday morning. Churchill Downs insists that the Derby will go off Saturday - even if storms cause post time to be pushed back later in the evening, something that's possible thanks to the installation of permanent floodlights at the track. The track was harrowed and sealed to prepare for the rain on Friday following the races, and the track may be closed to training Saturday morning.

Super choice: Derby waging began on Friday and Super Saver, who opened as a 15-1 shot on the board, is the early 7-1 favorite. Lookin at Lucky, the morning line favorite at 3-1, has drifted up to 9-1. No other entry is at single-digit odds. Original second choice Sidney's Candy, who was 5-1 on the morning line, is now 11-1. Ice Box, Devil May Care and Awesome Act were the original co-third choices at 10-1; they are now 11-1, 10-1 and 13-1, respectively. Make Music For Me, Dean's Kitten, Backtalk and Homeboykris all opened at 50-1; they are now 25-1, 18-1, 20-1 and 17-1. The longest shot on the board is Discreetly Mine at 41-1.

Recovering: Sunland Park Derby winner Endorsement, who suffered a fracture during what would have been his final Derby work on Wednesday morning, came through the repair surgery with flying colors at Rood and Riddle Equine Clinic. He vanned from Rood and Riddle to WinStar Farm today where he'll be laid up three to six months before returning to training. He is expected to make a full recovery and return to the races next year.
