The San Francisco 49ers secondary has some question marks http://www.sanfrancisco49ersteamonline.com/dante-pettis-jersey , and while we don’t have final answers, defensive coordinator Robert Saleh offered up some insight into the team’s approach.Strong safety Jaquiski Tartt has been dealing with a shoulder injury that limited him in practice last week. He aggravated the injury in the fourth quarter against the Lions, and is now missing practice in advance of the Chiefs game. He sat out Wednesday practice, and his status is uncertain for Sunday. Defensive coordinator Robert Saleh said Antone Exum, Tyvis Powell, and D.J. Reed are all getting work at strong safety. If Tartt cannot go on Sunday, I could see the team releasing linebacker Terence Garvin to promote Powell from the practice squad.Cornerback Ahkello Witherspoon is dealing with an ankle injury, and was listed as limited on Wednesday. Saleh would not commit to him being in the starting lineup on Sunday, but that could have as much to do with the ankle as with his struggles last week against Detroit. Richard Sherman hopes Witherspoon gets back into the starting lineup http://www.sanfrancisco49ersteamonline.com/earl-mitchell-jersey , but how he responds in practice will impact things.Trent Taylor listed as doubtful on 49ers final injury report, Matt Breida is a game-time decision The San Francisco 49ers released their final injury report in anticipation to their Monday Night Football game against the Green Bay Packers and Dante Pettis isn’t the only wide receiver to miss the primetime matchup. Trent Taylor will also be out for the game. The beat writers have also reported that Taylor will be out. Richie James had a few looks in Week 5, but with Taylor now sidelined, he has an opportunity to show some things and develop a role with the team. Matt Breida (shoulder/ankle), who many thought would not make the trip to Green Bay was listed as questionable and remains a game-time decision according to Kyle Shanahan. If put in the game, I’d imagine Breida would get limited snaps while Alfred Morris would be playing a bit more just so the 49ers don’t aggravate anything.The 49ers do have until Monday afternoon to make a decision on the roster for Monday Night, that will give them some time to evaluate the injuries and make some decisions.Meanwhile with the Green Bay Packers, quarterback Aaron Rodgers was not listed on the practice report at all. Rodgers suffered a knee injury in Week 1 that has been lingering since. Wide receivers Randall Cobb (hamstring) and Geronimo Allison (hamstring) are both game-time decisions, so Rodgers has even less people to throw to. 49ers injury reportOut: WR Dante Pettis (knee) http://www.sanfrancisco49ersteamonline.com/solomon-thomas-jersey , Doubtful: WR Trent Taylor (back)Questionable:RB Matt Breida (shoulder, ankle), WR Pierre Garcon (shoulder, knee), TE George Kittle (knee), G Mike Person (knee), C Weston Richburg (knee), T Joe Staley (knee), CB K’Waun Williams (illness)Packers injury reportQuestionable: CB Jaire Alexander (groin) Authentic Laken Tomlinson Jersey , WR Geronimo Allison (hamstring), CB Bashaud Breeland (hamstring), T Bryan Bulaga (knee), WR Randall Cobb (hamstring), G Justin McCray (shoulder), T Jason Spriggs (ankle), S Jermaine Whitehead (back)
