Injuries continue to mount in the early stages of the 2016 Monster Energy AMA Supercross, an FIM World Championship, series with James Stewart and Justin Bogle officially sidelined for Anaheim 2.

Yoshimura Suzuki Factory Racing’s Stewart will miss his second race in a row, still recovering from a concussion sustained at Anaheim’s opener.

Stewart rode late this week, but is still not feeling 100 percent fit to race the American event and is now expected to return to action for the following race in Oakland, California, on 30 January.

“James rode yesterday and today and felt he still wasn’t back to where he wants to be to race,” said Yoshimura Suzuki team manager Mike Webb today.

“The team is happy that James is taking a cautious approach to his return and we’re encouraged by his progress. We want him to feel fully-prepared before he gets back into a racing situation and with the improvements he’s making, he feels confident he’ll able to race in Oakland.”

Stewart’s teammate Blake Baggett has been back on the practice track and is getting back to fitness quickly. He was injured in a pre-season testing fall and is also slated to be back in action at Oakland.

GEICO Honda’s 450SX class rookie Bogle is also out for A2 after his crash during the San Diego main event and a pre-season foot injury. He’s not expected back until after Oakland.
