Keenan Allen WR SD 15 Hrs

Coach Mike McCoy confirmed that Allen (collarbone) won't play Saturday against the 49ers, the San Diego Union-Tribune's Michael Gehlken reports.

Meanwhile, Allen hasn't been ruled out for Week 17, but his status for that game looks iffy, at best, at this stage. With Allen out this week, at a minimum, fellow wideouts Malcom Floyd and Eddie Royal are candidates to see added looks in the Chargers' passing attack Saturday, along with Seyi Ajirotutu.

Andre Johnson WR HOU 15 Hrs

Johnson (concussion) practiced Wednesday.

Johnson's status is worth monitoring closely in the coming days, but his presence on the field Wednesday bodes well for his chances of suiting up Sunday against the Ravens, in the absence of any setbacks.

Ray McDonald DL SF 15 Hrs

The 49ers have released McDonald, the team's official site reports.

"We as an organization have notified (McDonald) and his agent that we have terminated his contract," GM Trent Baalke indicated Wednesday in a statement relayed by the 49ers' official site, following the team's release of the defensive tackle. "Ray has demonstrated a pattern of poor decision-making that is no longer going to be tolerated."

DeAngelo Williams RB CAR 16 Hrs

Williams (hand) was limited in practice Wednesday, David Newton of ESPN.com reports.

Williams fit in limited practices last week, yet he still was handed inactive status this past Sunday against the Buccaneers, marking his second DNP in a row. Clearly, the fractured finger in his hand is still hindering him, but as the week rolls on, his status for Week 16 against the Browns could receive clarity.

Ladarius Green TE SD 16 Hrs

Green (ankle) did not practice Wednesday, Michael Gehlken of the San Diego Union-Tribune reports.

We'll monitor Green's status in the coming days, but with fellow TE Antonio Gates healthy at this stage of the season, Green's fantasy upside is modest, in any case.

Julio Jones WR ATL 16 Hrs

Jones (hip) didn't participate in Wednesday's practice, D. Orlando Ledbetter of the Atlanta Journal-Constitution reports.

Jones has yet to make an appearance of any kind, practice or otherwise, since suffering a hip injury in Week 14 at Green Bay. According to Vaughn McClure of ESPN.com, coach Mike Smith relayed Wednesday that a decision won't me made regarding Jones' Week 16 availability until 11:30 AM ET on Sunday morning, meaning not much may be revealed by the release of Friday's injury report.

Ryan Mathews RB SD 16 Hrs1 Comment

Mathews (ankle) did not practice Wednesday, Michael Gehlken of the San Diego Union-Tribune reports.

Per the Chargers' official site, Mathews' status for Saturday's game against the 49ers is unclear at this stage. If Mathews is out again this weekend, or limited, Branden Oliver and Donald Brown would be in line to see added work in the Chargers' Week 16 backfield, along with Ronnie Brown to a lesser extent.

Philip Rivers QB SD 16 Hrs

Rivers (chest, back) wasn't spotted at practice Wednesday, Michael Gehlken of the San Diego Union-Tribune reports.

The report relays that Rivers was a spectator on Tuesday during the Chargers' individual drills, but the quarterback doesn't seem concerned about his Week 16 availability at this stage. "I feel good," said Rivers. 'I'll be ready to roll on Saturday evening."

Cam Newton QB CAR 16 Hrs

Newton (back) split reps with Derek Anderson in practice Wednesday, Joe Person of the Charlotte Observer reports. Afterward, coach Ron Rivera told NFL Network, "I like what I saw. Tomorrow will be a big day, especially in AM, to see where he is."

Newton's return to practice is an encouraging sign for his Week 16 availability, which will be confirmed, one way or another, by Rivera on Friday, when he'll confirm the Panthers' starting quarterback, according to Jonathan Jones of the Charlotte Observer. As a result, interested parties should tune in after the final practice of the week to learn if Newton will in fact be under center Sunday against the Browns.

Delanie Walker TE TEN 16 Hrs1 Comment

Walker (knee) is listed as questionable for Thursday's game against the Jaguars, Jim Wyatt of the Tennessean reports.

Per Terry McCormick of 247Sports, Walker believes that he will play Thursday, but given the official questionable designation, those planning to roll with the tight end (who caught four passes for 93 yards in Week 15) in their Week 16 lineups will want to verify his status as the Titans' 8:25 ET kickoff approaches.
