The upcoming World Extreme Cagefighting show set for Sept. 10 has undergone another change. MMAWeekly.com has learned that Tim McKenzie has been forced to drop off the card due to an undisclosed injury.

McKenzie was set to take on David Avellan in the 205-pound division, but as of now it appears the fight may get scrapped all together with Avallan's opponent out of the bout.

Following a disappointing return to the WEC that saw McKenzie lose to now champion Steve Cantwell, he got back to his winning form with a submission over Jeremy Lang in June.

No word has come down as to the medical reason behind McKenzie's departure from the show.

As of now, the WEC show still boasts a total of 10 bouts, which could mean that Avellan could be bumped to a future show, unless a last minute replacement steps in.
