Foot injury shelves Chargers’ Bosa

COSTA MESA, CALIF. » Los Angeles Chargers defensive end Joey Bosa will miss Sunday’s game at Buffalo because of a bone bruise to his left foot.

Coach Anthony Lynn said Thursday the team will be cautious before bringing the third-year lineman back. Bosa first injured the foot during training camp, which caused him to miss the preseason. He then reinjured it during practice on Sept. 5.

Bosa has 23 career sacks in two seasons, including an NFL-record 19 in his first 20 games.

Elbow issue shelves Roethlisberger for 2nd straight practice

PITTSBURGH » Pittsburgh quarterback Ben Roethlisberger missed practice again Thursday due to an issue with his elbow.

The 36-year-old Roethlisberger injured the elbow on Pittsburgh’s next-to-last offensive snap in a Week 1 tie with Cleveland. He did not practice on Wednesday and second-year quarterback Josh Dobbs took all the snaps with the starters on Thursday.

Offensive coordinator Randy Fichtner declined to get into specifics about Roethlisberger’s status for Sunday’s home opener against Kansas City.

Roethlisberger downplayed the significance of the injury on Wednesday. He often does not throw on Wednesdays during the season to help keep his right arm fresh. It is unusual for him not to practice on Thursdays.

Roethlisberger has not missed a start due to injury since October 2016.
