"Next week, for sure," Bush said as he left the locker room at TCF Bank Stadium.
Bush missed his first game of the season Sunday against the Vikings after not practicing all week with an ankle sprain. He injured the ankle during the Lions' 17-14 loss to Buffalo last week.
He has 45 carries for 161 yards this season and a touchdown along with 20 catches for 142 yards.
Joique Bell and Theo Riddick made up for Bush's absence. Bell had 74 yards and a touchdown on 18 carries along with two catches for 23 yards. Riddick had three carries for six yards and five catches for 75 yards and a touchdown for the Lions.
