Hillis practiced on Wednesday, but sat the last two days and was listed as questionable on Friday's injury report.
"He'll be out there and we'll decide again whether he's going to play or not on Sunday," said Browns coach Pat Shurmur. "So, we'll see."
Hillis didn't practice last week and missed Sunday's 6-3 win over Seattle. Montario Hardesty rushed for 95 yards on 33 carries in his place.
After breaking out last season with 1,177 yards and 11 touchdowns, Hillis has missed two games for the 3-3 Browns this year and has just 211 yards and two TDs on 60 carries.
Linebacker Auston English (knee) and wide receiver Mohamed Massaquoi (head) have been ruled out for the Browns.
