Darius Slay doubtful for Detroit Lions after "freak" injury

The Detroit Lions could be without cornerback Darius Slay for their clash against the Philadelphia Eagles on Sunday.

The rookie sustained a "freak" injury during his side's practice on Thursday and after having undergone tests earlier today, he has been listed as doubtful.

Head coach Jim Schwartz told the Detroit News: "He hurt his knee in practice yesterday and he's still being evaluated.

"We'll just see where that takes us. It was sort of a freak thing."

The Lions are 7-5 in their season going into their week 14 clash.
