The Raiders will be without starting right guard Gabe Jackson for approximately two months after he sustained a right knee injury Thursday during a joint practice with the Los Angeles Rams.
Coach Jon Gruden said following practice the Raiders were “really concerned” and although their worst fears weren’t realized — Jackson is not out for the season and will not need surgery — the five-year veteran doesn’t figure to return until October.
A source said Jackson would be out eight weeks with an MCL strain “give or take a few” depending on how fast he heals.
If Jackson is out eight weeks, he would miss the first four games of the regular season — Denver, Kansas City and road games against Minnesota and Indianapolis. After that, the Raiders face the Chicago Bears in London on Oct. 6.
Jackson is one of the Raiders most consistent lineman, and the hope was teaming him with Trent Brown would be create of the NFL’s most effective tandems on the right side of the line.
Jackson’s mishap was the first major injury of camp. Wide receiver Antonio Brown missed practice again with what is believed to be a condition similar to frostbite on both feet as a the result of a reported cryotherapy session.

Gruden continued to decline comment on anything to do with Brown.
“He’s still gathering (information),” Gruden said. “I don’t have any information other than that.”
Asked if the reports of frostbite were correct, Gruden said, “I’m not going to get into the exact nature of the feet. I’m just not.”
The Raiders believe Brown will be back soon, even if they don’t know have a timetable. As for Jackson, they’ll have to keep their fingers crossed.
Gruden said Jackson got “rolled up a little bit” during a team period. Moments earlier, Jackson had been involved in a minor skirmish with Rams defensive tackle Aaron Donald.
Jackson struggled to stand before he was placed on a cart and driven toward the field house and weight area where he was checked out by trainers. Owner Mark Davis made his way to the restricted area and spent between 10 and 15 minutes there before re-emerging to watch practice.
With Jackson out, Denver Kirkland took reps with the first team at right guard as did Jordan Devey, who is also the Raiders’ backup center to Rodney Hudson.
