INDIANAPOLIS -- Chuck Buckman says he has no memory of being struck by Danica Patrick's race car on pit lane Friday afternoon, and he hopes to soon put his concussion out of his mind, too.

Buckman, a chief mechanic for Dale Coyne Racing, was clipped by Patrick's car just after 2 p.m. Friday as she was trying to pit during practice for the Indianapolis 500. Buckman's head hit the Indianapolis Motor Speedway cement, briefly knocking him unconscious.

He was soon alert and was checked by medical personnel at the track and eventually at Methodist Hospital. He suffered a concussion, officials said.

In a statement released to the news media, Buckman said he would be fine.

"All I remember was talking to someone on (driver) Marco Andretti's team and then everything went blank from that point," Buckman said. "I will be OK and hopefully back to work in a day or two."

In brief comments to reporters about three hours after the accident, Patrick said she hoped Buckman would recover quickly.

"It's really, really unfortunate what happened today," she said. "Thoughts and prayers are with him and his family. Hopefully he can get back to the track soon and be able to do what he loves."

A spokesman for Patrick's team, Andretti Green Racing, said Patrick wouldn't comment further about the incident Friday.

Video recorded by ESPN showed Buckman was walking in a pit area -- perhaps trying to walk to one of his team's cars -- when Patrick, heading toward Buckman, struck him as she tried to pit.

Patrick's car appeared to clip Buckman with its left front and left rear tires.

6Sports reporter Kip Lewis saw the incident.

"You saw him trying to walk around (Marco Andretti's) car, who is a pit up from Danica's, and at the last second you could see (Buckman's) eyes turn," Lewis said. "He saw Danica coming into the pit; he couldn't get out of the way.

"He flipped into the air. It looked like he landed on his head, actually. Medics obviously got there to try to help him as fast as they could."

Dale Coyne Racing includes drivers Bruno Junqueira and Mario Moraes.

Rookie Lloyd Hits Wall

The incident happened not long after Indianapolis 500 rookie Alex Lloyd crashed into a wall during the practice session.

A neck brace was put on Lloyd, and he was taken to the track's hospital before he was transported to Methodist Hospital complaining of neck pain.

Information about Lloyd's condition wasn't available.

Rain Shortens Friday's Session; Dixon Fastest

Rain shortened Friday's practice session, leaving some drivers starved for practice time ahead of Saturday, the first day of qualifications.

Rain had prevented practice on Wednesday and Thursday, leaving most Indy 500 veteran drivers with only Tuesday and Friday's abbreviated session to prepare for Saturday. Rookies were able to drive on the track Sunday and Monday.

Scott Dixon posted Friday's fastest lap at 226.968 mph. Following him were Marco Andretti (226.710 mph) and Tony Kanaan (226.688 mph).

Sarah Fisher, who started her own team this season, made her first track appearance and was quickly up to more than 219.

Saturday's qualifying will be for the pole and the next 10 positions in the May 25 race. The rest of the 33 starting positions will be claimed on other qualifying days.
