ALLEN PARK — Neither LB Justin Durant or TE Tony Scheffler practiced today (Thursday). Both have concussions.

Scheffler suffered his in Monday night’s game and could not finish. No word on if it’s a long-term situation with him, but the Lions signed TE Joe Jon Finley who was at practice. Finley, who was on the Lions’ practice squad last season, was cut on Sept. 3.

Durant suffered his concussion against the Vikings. He practiced on a limited basis at the end of last week but didn’t see action on Monday night because concussion symptoms returned in the pre-game warm-ups.

Safety Amari Spievey, who sat out Monday with a hamstring, was on the practice field for the part of practice that the media is allowed to watch.

Also returning to practice were CB Aaron Berry and WR Rashied Davis.

Earlier today it was announced that S Erik Coleman has been placed on Injured Reserve, ending his season.

Last week the Lions signed veteran safety Vincent Fuller. With Spievey and Coleman out on Monday, Fuller saw game action. They have four safeties with Fuller and another, Ricardo Silva, on the practice squad.

ALLEN PARK — Eight Lions were missing from practice this afternoon including starters Calvin Johnson, Justin Durant (concussion), Stephen Tulloch and Amari Spievey.

Also out were Titus Young, Rashied Davis (foot), Erik Coleman (leg) and Jason Fox (foot).

Rookie Nick Fairley practiced for the first time since Sept. 29. That day was his only practice since he broke his foot early in training camp. That does not mean he will play on Monday, but it’s an encouraging sign.

Wednesday’s practice was a bonus day for the Lions (4-0) who will host the Chicago Bears (2-2) on Monday Night Football at a sold-out Ford Field.

The Bears had Wednesday off.

ALLEN PARK — Any question about why the Lions are not reporting agreements made with free agents, was cleared up Thursday morning when a team spokesman read the edict from the NFL.

Teams are not allowed to make announcements until a free agent is signed and they are not allowed to be signed until 6 p.m. on Friday. Negotiations started at 10 a.m. Tuesday.

Reportedly the Lions have agreed to a deal with outside linebacker Justin Durant who played the last four seasons at Jacksonville. A bit injury-prone, he’s never played 16 games in a season. Last year the 25-year-old played in 10, starting nine of those.

Durant confirmed the deal through a series of tweets on Wednesday night.

The Lions are reportedly also interested in linebacker Stephen Tulloch, a former teammate of Kyle Vanden Bosch’s with the Titans.

No word on the status of Chris Houston. Reportedly the Lions are also in play for cornerback Johnathon Joseph who spent last five seasons with Cincinnati.
