The Detroit Lions have lost another starter to concussion protocol days before their Thanksgiving game with the Buffalo Bills.
Left guard Jonah Jackson did not practice Tuesday for a second straight day and is unlikely to play Thursday because of a brain injury.
Jackson was designated as a non-participant on the Lions’ estimated practice report Monday because of an illness. On Tuesday, his designation was changed to out with a concussion.

The Lions will be without top cornerback Jeff Okudah against the Bills after he sustained a brain injury in a collision with teammate Will Harris in the second quarter of last week’s win over the New York Giants.
Lions coach Dan Campbell said Sunday there was not enough time for Okudah to clear the league’s concussion protocol and play Thursday. Players must be evaluated by an independent neurologist and “tolerate full participation practice and contact without signs or symptoms” before they can return to game action.
“He’ll be out,” Campbell said Sunday. “I mean, I can’t imagine. I’m pretty sure. We just talked about it. I don’t think there’s any way possible he can play.”
Campbell said the Lions will use a combination of Jerry Jacobs, Mike Hughes and Amani Oruwariye at outside cornerback in Okudah’s absence Thursday.
What they do on the offensive line is less clear.
Right guard Evan Brown was listed as a non-participant in practice Tuesday for the second straight day because of an ankle injury, and the team has been without Halapoulivaati Vaitai and Tommy Kraemer all season.

Dan Skipper replaced Brown against the Giants, and either Logan Stenberg or Kayode Awosika could start in place of Jackson.
Defensive linemen Charles Harris (groin) and Josh Paschal (knee) also were listed as non-participants on the Lions’ estimated practice report Tuesday, while receivers DJ Chark (ankle) and Josh Reynolds (back) and center Frank Ragnow (toe) were limited.
