Baltimore's quarterback room just got thinner on paper.

The Ravens officially placed Lamar Jackson and Tyler Huntley on injured reserve Thursday. Both will miss a minimum of four games.

Jackson hurt his right thumb on his first snap in Sunday's loss at Buffalo. Huntley suffered a toe injury in the same half after coming on in relief.

Season outlook still cloudy

Huntley's turf toe is already expected to end his season. Jackson had not yet had surgery as of Tuesday and coach Jesse Minter said the club still needed a clearer final answer on how long he will be out.

"I think it'll be at some point here that we know that for a final sure," Minter said earlier this week.

Who is left under center

Baltimore signed Austin Reed to the 53-man roster. He joins undrafted rookie Joe Fagnano and Kedon Slovis as the active quarterbacks for Thursday night against the Jacksonville Jaguars.

Fagnano will make his first career start. The Ravens are also finalizing a trade for veteran Jacoby Brissett. He would not be available until Monday Nov. 16 against the Los Angeles Chargers at the earliest.

The club also elevated kicker Jake Moody and outside linebacker Adisa Isaac from the practice squad for the Jaguars game.
