The Detroit Lions have listed cornerbacks Chris Houston and Darius Slay as doubtful for their game against the Baltimore Ravens tomorrow.
Houston has missed three practices this week with a toe injury, while Slay has sat out all week with a knee injury.
The NFC North leaders have just four healthy cornerbacks on their active roster.
Meanwhile, running back Reggie Bush and defensive end Ezekiel Ansah are both listed as questionable after missing time in the week, but both practised on Friday.
