Lions rule out Ansah; Tate, Davis questionable vs. Cowboys

Allen Park — The Detroit Lions keep having injuries crop up during the practice week. 

On Friday, wide receiver Golden Tate (hip) and linebacker Jarrad Davis (knee) made surprise appearances injury report. Both have been listed as questionable for Sunday's game against the Dallas Cowboys.

A day earlier, it was rookie guard Frank Ragnow who unexpectedly showed up on the practice report with a knee injury. That concern quickly alleviated when he returned to the field Friday, was a full participant, and wasn't listed among the team's game day designations. 

Lions coach Matt Patricia was asked how he balances the preferred physicality of his practice with maintaining the health of his roster. 

"In general, with this game, I feel that if you go out and practice at a high level and everybody practices at a similar tempo, I find that the injuries are less," Patricia said. "I think when the injuries increase, maybe, is when that tempo is taken down or (we’re) not particularly all on the same page, and you might have guys going at one percentage and another guy going at a different percentage." 

The Lions officially ruled defensive end Ziggy Ansah (shoulder) and tight end Michael Roberts (knee) out for the game against the Cowboys. Neither player practiced this week. 

It will be the third straight week Ansah has missed with the injury he suffered in Detroit's season-opening loss to the New York Jets. 

There was a No. 94 practicing, as defensive tackle Ricky Jean Francois squeezed into Ansah's uniform for the session.
