GRAND PRAIRIE, Texas -- Two skydivers were injured when they landed hard on their feet and knees during a performance after the sixth race at Lone Star Park on Saturday.

James Knight of Kaufman, Texas, was upgraded from critical to serious condition Saturday night at Methodist Medical Center in Dallas, nursing supervisor Karen Clark said. Track spokesman Darren Rogers said Knight, 56, suffered a broken right femur and a minor cut on his chin.

Wayne Keese of Grandbury, Texas, sprained his right ankle in the accident, Rogers said. Keese was treated and released.

Lone Star general manager Steve Sexton said the accident happened just before the $300,000 Lone Star Derby, the seventh race on Saturday's card.

"His chute opened, but he just came down harder than normal," Sexton said of Knight.

The accident delayed the race for about eight minutes as an ambulance crew treated Knight.

In the race itself, a 1 1/16th-mil event for 3-year-olds, Eibar Coa drove Ralph Ziadie-trained Tahkodha Hills from third at the clubhouse turn to victory.

In the eighth race about a half-hour later, Coa rode another Ziadie-trained entry, Sir Bear, to a win by a nose over Lexington Park in the $300,000, Texas Mile for 3-year-olds.

Tahkodha Hills broke second from the gate, fell to fourth by a length in the backstretch, then rallied to beat Jeblar Sez Who by two lengths in 1:44.05. The favorite, Big Numbers, finished third in the field of seven, two lengths behind Jeblar Sez Who.

Tahkodha Hills took $180,000 in earnings.

Ziadie said the horse probably will make his next start in the Belmont Stakes on June 10 to seek Lone Star Park's new $1 million bonus to any Lone Star Derby winner who goes on to also take a Triple Crown event.

In the Texas Mile, Barbara Smollkin's Sir Bear fell to seventh early in the field of nine before rallying down the backstretch. Sir Bear and Lexington Park then battled furiously from the clubhouse turn all the way to the wire, with Sir Bear prevailing by a head for a $170,000 payday. Southern California invader Luftikus ended up third.

Sir Bear completed the mile in 1:35.98 in his first win since the 1999 Metropolitan Mile Handicap in New York. Ziadie said the 2000 Metropolitan Mile will be Sir Bear's next start.
