Rothwell vs. Lins was originally scheduled for March 13 in Las Vegas, but got cancelled days before the fight due to an injury to Rothwell.
The UFC has yet to officially announce the venue and location for the Fight Night show, which is also without an announced main event.
Rothwell (38-13) was on a two-fight winning streak over Stefan Struve and Ovince Saint Preux prior to a decision loss to Marcin Tybura in his most recent bout in October 2020, dropping his overall UFC record to 8-7.
Lins (14-5), the 2018 PFL heavyweight champion, has yet to secure a win inside the octagon. The Brazilian fighter went 4-0 with the PFL in 2018 before suffering defeats to Andrei Arlovski and Tanner Boser in a span of seven weeks in 2020.
