. The team travels to face the Arizona Cardinals on Sunday Authentic Richard Sherman jersey , and then turns around to host the Oakland Raiders on Thursday Night Football in Week 9.The quick turnaround is of particular concern given the numerous injuries the team is dealing with at present. It takes several days for a healthy player’s body to recover from a Sunday game. Add in injuries and players are even less certain to be healthy. The NFL says there is not a notable increase in injuries on TNF, but they conveniently ignore the turnaround required for players to recover on a short week.Which brings us to Richard Sherman. The 49ers cornerback is dealing with a nagging calf injury that he and head coach Kyle Shanahan have said will be something to manage most of the rest of the season. He sat out Week 7 after playing Weeks 5 and 6. This week, he was limited on Wednesday and then downgraded to DNP on Thursday.Sherman met with the media on Thursday before practice. He said he’ll work the calf and see how it feels each day. If it feels good, he’ll play Youth Weston Richburg jersey , if not, he’ll shut it down. He said he was “pretty sure” he would be able to play this Sunday vs. the Cardinals, but next Thursday was a question mark. When asked if he would only be able to play one of the games, he said it was a possibility http://www.49ersauthorizedshops.com/authentic-kyle-juszczyk-jersey , but he’ll work to try and play in both.Richard Sherman misses Thursday practice with heel injury The San Francisco 49ers were back at practice Thursday afternoon, and a notable name was added to the injury list. Cornerback Richard Sherman was a DNP and listed with a heel injury. By all accounts he was walking around fine, but he spent practice working on a side field.My guess is this more precautionary than anything else, but Friday’s final injury report coupled with Kyle Shanahan’s end of week press conference will offer some clarity on Sherman’s status. If he is fine Pierre Garcon jersey , so be it. If he develops into a question mark for Sunday, the 49ers have some serious issues at hand in the secondary.Ahkello Witherspoon was limited again with an ankle injury, but the 49ers also added a hip mention to the injury report. When asked how Witherspoon responded in practice this week, defensive coordinator Robert Saleh was said he came out strong mentally. He acknowledged the second year cornerback had some physical issues he still had to work through.Finally Authentic Laken Tomlinson jersey , Jaquiski Tartt was a DNP for the second straight day due to the shoulder injury he aggravated last Sunday. Antone Exum is getting first string work in Tartt’s place, and Tyvis Powell and D.J. Reed are getting work there as well.That’s three-quarters of the starting 4-3 secondary, and three-fifths of the starting nickel secondary. Getting ready to face a white-hot Chiefs squad, this is very much a bad thing. But again Youth Marquise Goodwin jersey , Friday’s injury report is what we’re waiting for before we can make firm assessments.
