UFC 41: Onslaught took place at Boardwalk Hall in Atlantic City, New Jersey, on 28 February 2003. Tim Sylvia took the heavyweight title from Ricco Rodriguez, while B.J. Penn and Caol Uno finished their lightweight championship bout without a winner. The card also contains a useful distinction for anyone checking old results: a draw and a corrected announcement are different outcomes.
All eight UFC 41 results
The first name is the winner except in the explicitly marked draw. Round and time are separate: the clock shows time within the final round, not the entire fight. KO/TKO groups stoppages by strikes without claiming a more specific finishing sequence.
| Result | Method | Round, time |
|---|---|---|
| Tim Sylvia defeated Ricco Rodriguez | KO/TKO; heavyweight title | 1, 3:09 |
| Frank Mir defeated Tank Abbott | Submission: toe hold | 1, 0:46 |
| B.J. Penn drew with Caol Uno | Split draw; lightweight title | 5, 5:00 |
| Matt Lindland defeated Phil Baroni | Unanimous decision | 3, 5:00 |
| Vladimir Matyushenko defeated Pedro Rizzo | Unanimous decision | 3, 5:00 |
| Gan McGee defeated Alexandre Dantas | KO/TKO | 1, 4:49 |
| Din Thomas defeated Matt Serra | Split decision | 3, 5:00 |
| Yves Edwards defeated Rich Clementi | Submission: rear-naked choke | 3, 4:07 |
The UFC event record supplies the complete card and its round/time fields; the linked athlete records and reports clarify outcomes. Some win/loss labels in the event page conflict with those records, so they should not be copied mechanically.
Why Penn–Uno remained a draw
UFC's published fight recap records three cards: 48–47 for Uno, 48–46 for Penn, and 48–48. Lay them out with the same fighter in each column:
| Card | Penn | Uno | Card favours |
|---|---|---|---|
| Uno's card | 47 | 48 | Uno |
| Penn's card | 48 | 46 | Penn |
| Even card | 48 | 48 | Neither |
That gives one card to each fighter and one even card. Adding across judges would produce 143–142 for Penn, but that calculation does not replace the recorded split draw. It is a useful spreadsheet check: preserve each judge's verdict instead of inventing a winner from a combined points total.
The UFC lightweight title history identifies this as the final of a four-man tournament and says the title remained vacant. It next records Sean Sherk winning the vacant belt against Kenny Florian at UFC 64 on 14 October 2006. A vacant championship should not be confused with an absence of all lightweight competition; the same history records lightweight activity between those dates.
Why Thomas–Serra belongs in the win column
In a 2013 UFC interview with Serra, the promoter describes a scoring error that changed the initially announced result. Serra recalled having his hand raised before learning that Thomas had won. The UFCStats record lists Serra's loss by split decision.
For a results sheet, record Thomas: win; Serra: loss, with the announcement correction in a separate note. For Penn–Uno, record a draw for both. Combining those situations under “controversial result” loses the information a reader needs. The interview supports the correction; it is not a substitute for an original signed scorecard, so this guide does not identify a judge or reconstruct which box was changed.
What the fight clocks show
Counting the completed bouts gives four finishes, three decision wins and one draw. Edwards–Clementi illustrates why the round matters: two completed five-minute rounds + 4:07 = 14:07 of fighting. Mir–Abbott's first-round 0:46 requires no earlier rounds to be added.
For a replay worksheet, keep three columns: final round, time in that round, and calculated fighting time. Breaks, introductions and post-fight coverage belong outside that calculation. A submission can happen near the end of a long bout or within its opening minute; the method alone does not tell you the duration.
Revision and sources
Revised 13 September 2026: this complete replacement verifies the result ledger and distinguishes the draw from the announcement correction. Unsupported medical, bonus and promotional assertions from the earlier version have been removed; omission does not establish that they were false.
