OWINGS MILLS, Md. — Carrying a three-game losing streak and a losing record, the Baltimore Ravens now face the burden of uncertainty at the quarterback position.

Joe Flacco is nursing a hip injury that could keep him out of Sunday’s game against Cincinnati, an AFC North matchup that carries huge ramifications for the sagging Ravens.

With Baltimore coming off a bye, Flacco received an additional week of rest and treatment after sustaining the injury on Nov. 4 in the opening minutes of a 23-16 loss to Pittsburgh.

Flacco went the distance, completed 23 of 37 passes for 206 yards. His status this week, however, is unclear.

“He’s getting treatment, just like all the guys are getting treatment, and we’ll see,” coach John Harbaugh said Monday. “I’d say that we’ll know more as the week goes on and I’m hopeful all our guys play, including Joe.”

If Flacco can’t play, rookie Lamar Jackson will likely get his first NFL start, although veteran Robert Griffin III is also an option. Griffin gets the nod in NFL experience, but he’s been inactive in every game this season.
