Saturday’s Supercross Round 3 in Houston: How to watch, start times, schedule, TV info

Leigh Diffey, Ricky Carmichael, and Will Christien discuss Ken Roczen’s penalty from Round 2, Dylan Ferrandis’ surprise start, Jett Lawrence’s first 250SX win, and how a new layout for Round 3 may trip up riders.

The Monster Energy AMA Supercross season has claimed its first factory rider casualty heading into Round 3 at Houston.

Chase Sexton, a heralded 450 rookie after winning the past two 250 East championships, announced Thursday he would miss Saturday’s event after injuring his right shoulder in a crash Tuesday after leading six laps in Round 2. Sexton got crossed up in a tricky sand section of the track and went sailing head first over his Honda.

Describing the shoulder as “weak” and lacking range of motion, Sexton wrote on Instagram that he would be returning to Florida for an MRI to check on internal damage. The Honda rider hopes he can return for the Jan. 30 event in Indianapolis, kicking off a three-race stretch in the city.

FIVE THINGS TO WATCH: Supercross storylines for the 2021 season

CONTROVERSIAL CALL: Ken Roczen wasn’t happy by how he was penalized in Round 2

Sexton’s crash was among the major developments in an eventful second race in Houston. Ken Roczen lost the points lead after a postrace penalty, and defending series champion Eli Tomac recovered from a mediocre showing in the season opener for his 35th career victory.

He moved to sixth in the standings, four points behind leader Justin Barcia, while Roczen dropped to fifth, three points out of first heading into the last of three consecutive rounds to open the season in Houston.
