Gray (concussion) did not practice Wednesday, Jim Wyatt of the Titans' official site reports.

Gray was concussed in the fourth quarter of last Sunday's loss to the 49ers and is in danger of missing his first game of the season. The 23-year-old linebacker has started all 14 games, posting a whopping 144 tackles (85 solo), including 1.0 sacks, four pass breakups and a pair of fumble recoveries on 90 percent of the defensive snaps. James Williams would likely be in line for increased reps if Gray is unable to face the Chiefs on Sunday.

The Packers activated Lloyd (calf/hamstring) from injured reserve Wednesday, per the NFL's transaction log.

According to Rob Demovsky of ESPN.com, this move is merely procedural so Green Bay can place him back on IR with the aim to get him back in the playoffs at some point. If said transaction occurs before Saturday's contest at Chicago, Lloyd would be eligible to return as soon as the divisional round. For the time being, though, the Packers will roll with the combination of Emanuel Wilson and Chris Brooks (chest) behind No. 1 RB Josh Jacobs (knee/ankle).

Delpit (groin) was limited in Wednesday's practice, Mary Kay Cabot of The Cleveland Plain Dealer reports.

Delpit was limited in practice last week but didn't carry an injury designation into last Sunday's loss to the Bears. The 27-year-old has appeared in all 14 games this season (13 starts) and has logged 67 tackles (34 solo), including 1.0 sacks, four pass breakups, including one interception, two fumble recoveries and one forced fumble on 95 percent of the defensive snaps.

Lockett (knee) was limited at practice Wednesday.

Lockett sustained a wrist injury in Sunday's 31-0 loss to the Eagles, but Wednesday's injury report instead lists the wideout as dealing with a knee issue. In any case, Lockett has two more opportunities to practice fully before the Raiders assign injury designations ahead of this weekend's game against the Texans. Assuming he's available, Lockett's only a lineup option in deeper fantasy formats, with the Raiders having dropped eight straight games and set to face a stingy Houston defense in Week 16.

Schwesinger (ankle) was limited in Wednesday's practice, Mary Kay Cabot of The Cleveland Plain Dealer reports.

Schwesinger has been limited in practice with the ankle injury for the last few weeks but has continued to play through the ailment. The second-round rookie linebacker has started all 14 games this season, producing 133 tackles (59 solo), including 1.5 sacks, and three pass breakups, including a pair of interceptions.

Johnston (groin) was a limited participant in practice Wednesday.

Rookie wideout Tre' Harris took on an 84 percent snap share with Johnston absent for Sunday's 16-13 win over the Chargers. Johnston was a late addition to last week's injury report, and while the issue doesn't seem serious, he may need a full practice Thursday/Friday to enter this weekend in good shape for Sunday's favorable matchup with Dallas.

Bigsby (illlness) was a full participant in Wednesday's practice.

Bigsby should be back at full strength for Saturday's game against Washington, if he isn't already. He took 17 carries for 57 yards during Sunday's 31-0 win over the Raiders, but 13 of those carries came in the fourth quarter after Saquon Barkley was done for the day. Barkley (neck) was also a full practice participant Wednesday, leaving Bigsby in his usual reserve role this week.

Smith (shoulder/back) practiced fully Wednesday.

Adam Schefter of ESPN previously reported that coach Pete Carroll said there was "a good chance" that Smith would rejoin the lineup Sunday against the Texans, and the QB's full practice participation Wednesday sets the stage for that to occur. With Smith inactive in Week 15, Kenny Pickett struggled to get the Raiders offense going in a 31-0 loss to Eagles (the team's eighth straight defeat). In his looming return to action, Smith only merits fantasy consideration in deeper, QB-friendly formats while facing a stout Houston defense.

Barkley (neck) was a full participant in Wednesday's practice.

Listed as a non-participant one day earlier, Barkley quickly returned to full participation and should be ready for his usual workload Saturday against Washington.

Weaver (hamstring) was limited at Wednesday's walkthrough, Zach Gershman of the Cardinals' official site reports.

Both Weaver and Marvin Harrison (heel) returned to the practice field Wednesday, but both players have some work to do to prove their respective levels of health ahead of Sunday's game versus the Falcons. Currently, Michael Wilson and Jalen Brooks are the only healthy wide receivers on Arizona's active roster.
