Rapid Redux is entered Wednesday to put his 21-race winning streak on the line, but he might not make it to the starting gate.
The gelding, now 6 years old with the start of 2012, is the 3-5 morning-line favorite for race No. 6 at Laurel Park in Laurel, Md., a $17,000 starter allowance event.
But trainer David Wells told Laurel officials on Tuesday that Rapid Redux "grabbed a quarter" in his right front foot a few days ago. That's an injury that occurs when a back hoof catches a bit of a front foot.
"There is a little cut on his right front foot," Wells said. "We are a little bit concerned about (Wednesday). It is kind of up in the air. We are working as hard as we can to get it healed up for where it isn't tender.
"It does bother him to push on it. It is a little spot, the size of a thumbnail. I had the blacksmith take off his glue-on shoes because we thought that was aggravating, but it is all coming from where he grabbed himself."
Rapid Redux has specialized in starter allowance races while establishing the longest winning streak in modern US racing. The previous mark of 19 was shared by Zenyatta and Peppers Pride.
The streak began Dec. 2, 2010 at Penn National. Rapid Redux has won at seven different tracks during the streak.
Seven horses are entered to challenge Rapid Redux in a one-mile race Wednesday. If he runs, he will break from the second post position but wear saddle cloth No. 3 because the race includes a coupled entry.
