The Cowboys are leaning toward playing quarterback Tony Romo in Sunday's game at Philadelphia, but injuries to the offensive line will help make the final determination, sources said.

Left tackle Tyron Smith will not play after aggravating his right knee injury against the Lions on Monday night. Left guard Ron Leary, who didn't practice this week, is questionable. So the Cowboys want to be cautious with putting Romo — injured in three of the past five games he has played, including preseason — behind a makeshift offensive line.

ESPN reported Friday morning that Romo would play for the first time since Thanksgiving Day 2015. But Cowboys coach Jason Garrett said his staff will meet Saturday to formulate their final plans.

"Tony, like with all of our players, we haven't made those determinations," Garrett said. "The team has done a really good job of staying locked in on what we need to do."

The Cowboys will make three quarterbacks active for the first time this season, with rookie Dak Prescott making his 16th start of the season. Third-stringer Mark Sanchez, inactive the past six games, also is expected to play.

"Tony got some work; Sanchez got some work; Dak got some work," Garrett said of practice repetitions this week. "Guys at other positions got a lot work."

Floyd learning

Tom Brady said wide receiver Michael Floyd's fast-paced introduction to the complicated New England offense is coming along well.

"He's worked really hard to try to get up to speed," the quarterback said Friday. "… It's been good to see his commitment, and hopefully he can go out there and play confident and, like all of us, try to go get a win. "

Floyd, picked up by the Patriots after the Cardinals released him following his DUI arrest in Arizona, caught one pass in the Patriots' 41-3 blowout of the New York Jets last weekend. His contributions could increase Sunday in Miami, with rookie receiver Malcolm Mitchell questionable after missing practice all week with a knee injury.

Floyd, a former Cretin-Derham Hall star, has been putting in extra time with third-string quarterback Jacoby Brissett. "It's going well," Floyd said. "I'm getting more comfortable with the offense every single day, so that's a good thing."

Two Chiefs fined
