Dallas quarterback Tony Romo, who missed practice Wednesday due to ankle and back injuries, returned to practice on a limited basis on Thursday.

Romo’s left ankle was clearly taped. He was able to work on passing drills, but did not participate in drills that involved handing the ball off to running backs.

Romo underwent electric stimulator therapy on his ankle earlier in the week. He said he would be good to go against the New York Giants on Sunday.

Running back DeMarco Murray, the league’s leading rusher, and offensive lineman Tyron Smith also were back at practice on Thursday.

Murray sat out Wednesday with an unspecified illness.

Smith, had an MRI on his injured left ankle, hours after the Pro Bowl left tackle was named the NFC’s Offensive Player of the Week. The MRI came back negative and Smith vowed he would be “all right.”
