Ravens linebacker/defensive end Terrell Suggs said he is going to be a game-time decision as he works through a knee sprain in preparation for the Detroit Lions.

Suggs saw his first action on a limited basis this week for the first time since he left a Nov. 16 contest against the Cleveland Browns after quarterback Brady Quinn dove into his knee.

“I’m just trying to feel it out,” Suggs said Thursday.  “I don’t really want to go [full speed] before it’s ready, and it’s not ready. I’m trying to see how it feels in game situations. So, I guess we’ll just have to wait and see on Sunday.”

Suggs said he still must gain trust in the knee, but its condition has improved.

“It does feel better, but it still has some issues,” he explained.  “I’m still not trusting it fully all the way, but who knows? As the week goes on… It’s a long way away from Sunday.”

For the second consecutive day, the Ravens were without safety Ed Reed  (groin/foot), wideout Mark Clayton (knee), offensive tackle Jared Gaither (foot), lineman David Hale (head), linebacker Jarret Johnson (back) and tight end L.J. Smith (ankle).

Kicker Billy Cundiff, who sustained a concussion against the Packers, and defensive tackle Brandon McKinney (back) were limited, and quarterback Joe Flacco (knee/hip) fully participated.

For the Lions, tight end Casey FitzSimmons (concussion), defensive tackle Andre Fluellen (groin), defensive tackle Grady Jackson (knee) and quarterback Matt Stafford (left shoulder) did not practice.  Fluellen and Jackson were downgraded from being limited on Wednesday.

Defensive tackle Joe Cohen (knee), safety Louis Delmas (ankle), punter Nick Harris (left knee), offensive tackle Daniel Loper (back), safety Kalvin Pearson (hamstring), linebacker Ernie Sims (hamstring) and defensive end Dewayne White (toe) were limited.

Wideout Eric Fowler (knee) and cornerback Will James (neck) fully practiced.
