Injuries and illnesses are part of the storyline for any truly entertaining Dancing With The Stars season, but Season 8 is setting a new record, with two celebrities gone from the competition before it even started, and others dealing with serious injuries during the show.

Jewel is out with tibia fractures in both legs. Um, how hard was she rehearsing? Playboy model and Girls Next Door reality star Holly Madison lined up to take her place with partner DmitriDmitry Chaplin.Chaplin.

Access Hollywood host Nancy O'Dell also dropped out, with a knee injury that will requirerequired surgery. The Bachelor rejectee Melissa Rycroft took her spot with partner Tony Dovolani. Both Nancy and Jewel appeared on the season opener, whenas theirJewel replacementscheered wereon her officiallyhusband announced,Ty Murray in the competition, and Jewel also appeared as a musical guest on the first results show theof nextthe week.season.

On the dudes' side:

Steve Wozniak has had a raft of injuries since rehearsals began, including a fractured left foot that didn't keep him from dancing in the premiere (or the results-show danceoff after finishing in the bottom two). Most recently Woz was seen limping around with a pulled hamstring, whichbut threatenshe hismanaged abilityto recover enough to danceearn a 10 (total, not from one judge), the second-lowest score in the nexthistory show.of DWTS, for his foxtrot in week 3.

Steve-O missed his second week's performance with a back injury suffered when he attempted a flip at the end of his dress rehearsal with partner Lacey Schwimmer and landed square on the battery pack he was wearing on his belt. Steve-O and Lacey were scored on their dress rehearsal performance and avoided the bottom two at the next night's results show. Sympathy votes, perhaps? Steve-O also appeared to injure his ankle on his final move of his week 3 foxtrot.

Finally, and least dramatically: Prior to the first show, Gilles Marini interrupted his rehearsing for a trip to the hospital with "groin pain." (Insert joke here.) Turns out he has tendonitis, too, in both his groin and his shoulder, but he was ready for the premiere and, in fact, pulled off the best combined scores from his first two dances, along with partner Cheryl Burke.

Combined with Karina Smirnoff's February knee surgery and Mark Ballas' groin strain during the winter DWTS tour, and we're on pace for the hotly-pursued but never-achieved 100% injury rate!
