The New York Jets' starting QB is TBD for Sunday.

Sam Darnold and Josh McCown were both limited at practice for the second straight day, leaving it uncertain who will be under center at Tennessee.

Coach Todd Bowles said Thursday that Darnold, McCown and Davis Webb each had snaps and ran the offense during drills.

"We'll see who's the healthiest," Bowles said. "All of them are taking reps right now and we'll make that decision as the week goes."

It would appear the choice will come down to either Darnold or McCown, especially since Webb hasn't yet taken a regular-season snap in the NFL and was on the practice squad until Darnold was hurt.

Darnold has missed the past two games with a strain in his right foot. He showed progress Wednesday by participating in team drills for the first time since being injured against Miami on Nov. 4. Bowles said Darnold had no soreness in the foot Thursday, and wouldn't rule out starting the rookie even if he's limited Friday.

McCown is dealing with a sore hand and back. His right hand was cut when he banged it on a helmet during the Jets' loss last Sunday to New England. McCown played through it, though, and could be in line for his third straight start if Darnold isn't ready to play.

More surgery for Kelly

The wife of Buffalo Bills Hall of Fame quarterback Jim Kelly says her husband has undergone what is hoped to be his last cancer-related surgery.

On Instagram on Wednesday, Jill Kelly posted a picture of the former football player giving a thumbs-up sign from a hospital bed in New York City. Her comment said "all went as planned!"

In an earlier post, Jill Kelly said doctors told the couple it should be the 58-year-old's last surgery.

Kelly last underwent surgery in March when doctors at Mount Sinai Health System removed cancer from his upper jaw and lymph nodes and reconstructed his upper jaw.

A portion of Kelly's jaw was removed in 2013 after Kelly was first diagnosed with squamous cell carcinoma.

Flacco back at practice

Baltimore Ravens quarterback Joe Flacco has returned to the practice field for the first time since injuring his right hip on Nov. 4.

Having finally received medical clearance to play, Flacco threw passes and worked on handoffs with fellow quarterbacks Lamar Jackson and Robert Griffin III during an indoor practice.

Jackson, a 2018 first-round pick, led Baltimore to wins in each of the past two games while filling in for the injured Flacco. Although coach John Harbaugh has not named a starting quarterback for Sunday's game in Atlanta, it appears likely Jackson will get the call.

Flacco has missed only eight games in his 11-year career and had played in 41 consecutive regular-season games before injuring his hip against Pittsburgh in Week 9.
