A look at Thursday’s 15 preseason games

All eyes will be on Colin Kaepernick, who has vowed to continue his protest and sit during the national anthem. He gets his final shot to earn back San Francisco’s starting quarterback job. Kaepernick looked rusty last week in his first game action since November.

San Diego’s first round draftee, DE Joey Bosa, finally signed, but is expected to sit out.

Although running back Todd Gurley won’t be allowed near the field, coach Jeff Fisher still intends to evaluate several competitions for roster spots, particularly along the offensive line and in the secondary.

Vikings quarterback Shaun Hill, a 15 year veteran who will take over following the season ending knee injury to Teddy Bridgewater, probably won’t play against his former team.

Newly elevated starting QB Trevor Siemian isn’t going to play. Rookie Paxton Lynch, who acknowledges he’s had trouble digesting large chunks of the playbook, is scheduled to play the entire game with Mark Sanchez available in a pinch.

Matt Barkley is expected to play the entire game because coach Bruce Arians has no other option if he plans to sit QBs Carson Palmer and Drew Stanton. All Pro S Tyrann Mathieu (knee surgery) and WR John Brown (concussion) are cleared to play but probably won’t.

The Raiders have few remaining questions this preseason although coach Jack Del Rio said he would like to get another look at rookie middle linebacker Cory James before deciding whether James or second year player Ben Heeney will start the season.

Expect to see Seahawks No. 1 RB Thomas Rawls for a few plays.

The Colts are trying to avoid getting anyone else hurt. Four offensive linemen are out: Joe Reitz, Hugh Thornton, Joe Haeg and Jack Mewhort.

One of the most competitive spots for the Bengals is punt returner. Alex Erickson, an undrafted rookie who started his career at Wisconsin as a walk on, has an 80 yard touchdown return. Second round pick Tyler Boyd also had a pair of returns, including a 24 yarder.

Tom Brady’s final opportunity to play before his four game "Deflategate" suspension kicks in, and he said he would like to be on the field. Not likely.

The Giants brought back veteran tackle Will Beatty, but he has not practiced and isn’t likely to play.

Jaguars second round draft pick Myles Jack moved from middle to outside linebacker this week and will play extensively against Atlanta. Jacksonville also expects to get a lengthy look at QB Brandon Allen and rookie DT Sheldon Day, who missed the first three preseason games (back injury).

Matt Ryan will play against Jacksonville after throwing an interception and completing only 12 of 22 passes last week. Kicker Matt Bryant returns after missing two games with tightness in his leg.
