UFC 271 weigh-in results: William Knight misses by 12 pounds turning fight into heavyweight bout, one fight canceled


William Knight had a massive weight miss on Friday.

The light heavyweight made history at the UFC 271 official weigh-ins, coming in way over the 205-pound limit (plus one-pound allowance) as he stepped onto the scale at 218 pounds for his bout with Maxim Grishin (206). Knight’s 12-pound miss set a dubious UFC record, surpassing the 11. 5-pound weight miss of Rafael Alves from UFC Vegas 19 last February.

However, shortly after Knight weighed in, it was announced that his bout with Grishin would now be contested at heavyweight with Knight forfeiting 40 percent of his purse as penalty.

That was not the only problem at Friday’s official weight-ins. Alex Perez came in at 128 pounds, two pounds over the limit for his flyweight bout against Matt Schnell (126). UFC officials informed MMA Fighting later that Schnell had declined to fight. This is the fourth time that a bout between Perez and Schnell has fallen through.

Headliners Israel Adesanya and Robert Whittaker made weight without issue, with both champion and challenger hitting the mark at 184 pounds.
