Hillis returned to practice for the first time since Oct. 16 on Wednesday but suffered a setback and has missed the past two days. He was not on the field with his teammates Friday as the Browns went through their final practice before leaving for the West Coast.
"He'll be out there and we'll decide whether he's going to play or not," Shurmur said after practice. "We'll see."
Hillis' season has been a constant soap opera with his contract negotiations to secure a long-term extension, a strep throat sickness that caused him to miss a game and the hamstring injury among the main issues that have dominated his second season in Cleveland. He has vowed to stop talking publicly about his contract.
"I'm not going to be a distraction," he said.
Kicker Phil Dawson (right thigh) and linebacker Scott Fujita (head) are probable after fully practicing Friday.
