Yoel Romero’s big knockout of Luke Rockhold at UFC 221 this past weekend wasn’t enough to stop other middleweights from making a push for a title shot against champ Robert Whittaker.

Chris Weidman (14-3 MMA, 10-3 UFC), in particular, is one fighter who believes he, and not Romero (13-2 MMA, 9-1 UFC), should be the next to challenge for Whittaker’s (19-4 MMA, 10-2 UFC) belt.

If things had gone according to plan at UFC 221, Romero’s third-round knockout of Rockhold would have made him the interim 185-pound champion and set him up for a unification match with “The Reaper.” Romero missed weight for the event, though, and his victory as somewhat tainted.

Despite the botched weigh-in, UFC President Dana White confirmed Romero will indeed fight Whittaker next. Weidman hopes to change the mind of the UFC brass, though, and made his argument on social media (via Twitter):

Although Weidman makes a reasonable case, the immediate hole that will be poked into his argument is the fact the former champion is just 1-3 in his past four fights, including a decisive knockout loss to Romero at UFC 205 in November 2016.

After starting his career with 11 straight wins, including capturing the title and defending it three times, Weidman fell into a slump with three consecutive losses. He managed to rebound over the summer, though, submitting Kelvin Gastelum in the main event of UFC on FOX 25 in July.

Now Weidman wants the chance to fight Whittaker and become the first in UFC history with multiple middleweight title reigns.
