Baltimore Ravens

Injuries have hit the Ravens hard.

QB Joe Flacco hasn’t played in the preseason, but the team has maintained that his back injury will be healed in time for the Sept. 10 opener.

Expected starters or contributors at running back and tight end have been lost to injuries, and a remade receiving corps has been limping along.

But the defense should be stout against the run, and OLB Terrell

Suggs should have help in the pass rush from Z’Darius Smith, OLB Matthew Judon and rookie OLB Tim Williams. C.J. Mos

ley remains one of the NFL’s top middle linebackers, and the Ravens paid big to keep DT Brandon

Williams (five-year, $54 million deal) because he’s one of the league’s best run stuffers.

Rookie watch: Williams slipped to the third round because of off-field issues and questions about whether he was more than a pass rusher. For now, the Ravens don’t need him to be anything more than that and are excited about his natural ability and progress. He has an explosive first step and a knack for getting to the ball, and the Ravens think he’ll be ready for a big role this season.

Noteworthy: Head coach John Harbaugh was given a one-year extension through the 2019 season, according to the

Baltimore Sun. ... Undrafted rookie RB Taquan Mizzell continues to make a strong case to be on the regular-season roster. Veteran RB Danny Woodhead is dealing with a hamstring injury, so the Ravens might keep an extra running back on their roster. ... WRs Chris Moore and Keenan Reynolds and veteran Michael

Campanaro are on the bubble.
