San Francisco 49ers

San Francisco 49ers running back Christian McCaffrey (Achilles, calf) was on the practice field in uniform with the rest of the team on Thursday for what was not a fully padded session. McCaffrey was listed as limited for the first practice of the week on Wednesday and probably will end up with another limited designation on Thursday. Still, the fact that the 28-year-old is practicing at all after being a surprise inactive in Monday night's win over the New York Jets is good news. Last year's rushing champion is reportedly dealing with Achilles tendinitis in addition to a calf injury he suffered early in training camp. CMC hasn't been ruled out for Week 2 against the Minnesota Vikings, but signs are pointing to him being unlikely to suit up as the 49ers play things extra cautious with their star back. If McCaffrey is held out again this Sunday, Jordan Mason will be a must-start in this high-scoring 49ers offense as the lead back.UPDATE: McCaffrey was listed as limited again on Thursday.

San Francisco 49ers wide receiver Jauan Jennings (ankle) was a limited participant in the team's first practice of the week on Wednesday, which was a light walkthrough. Jennings briefly left the field in Monday night's win over the New York Jets due to an ankle injury, but he returned to the action and caught all five of his targets for 64 yards. He played just under half of the team's offensive snaps and likely had an elevated role with Deebo Samuel Jr. being more involved in the backfield and with the team easing Brandon Aiyuk back in after a lengthy contract hold-in during training camp. The 27-year-old's ankle injury likely isn't serious enough to keep him sidelined for a Week 2 tilt against the Minnesota Vikings, but if it is, Chris Conley and Ronnie Bell would compete for more playing time. Jennings is currently rostered in only 1% of Yahoo leagues.

San Francisco 49ers running back Christian McCaffrey (Achilles, calf) will continue to practice in a limited fashion on Wednesday, according to Cam Inman of the Bay Area News Group. McCaffrey was unable to play in the season opener due to a calf/Achilles issue. Inman further reported that the star running back has never been considered to be placed on the injured reserve, as he "could have played last week," according to head coach Kyle Shanahan. While McCaffrey is still in a limited fashion, seeing him on the practice field is a good sign for his progress. Fantasy managers should continue to monitor the situation, as he could be nearing a return. If the 28-year-old does not suit up for their Week 2 matchup against the Minnesota Vikings, Jordan Mason should be expected to lead the backfield once again and a be high-end RB2 on Sunday.

According to NFL Network's Ian Rapoport, San Francisco 49ers running back Christian McCaffrey (calf/Achilles) feels like a long shot to play in Week 2. McCaffrey was a surprise inactive in Week 1 and backup Jordan Mason filled in admirably in the team's runaway win over the Jets on Monday night. Mason could be in line for another big week with McCaffrey likely out based on this report. McCaffrey is dealing with a calf issue as well as Achilles tendinitis and the 49ers may be playing it safe early in the season with their star running back. Mason rushed 28 times for 147 yards and a touchdown in Week 1 and added a catch for five yards so he is clearly capable of filling in for McCaffrey. Fantasy managers of McCaffrey will hope he returns in a full capacity in Week 3.

San Francisco 49ers running back Christian McCaffrey (calf, Achilles) is in danger of missing two straight games. The superstar back was declared inactive a few hours before the season opener against the New York Jets on Monday. There was some controversy about backup running back Jordan Mason knowing he was going to start on Friday, but the team insisted that McCaffrey was a game-time decision. Now, it sounds like McCaffrey could sit out against the Minnesota Vikings this weekend. It's a short week and Minnesota does play on a turf, so it wouldn't be shocking to see the 49ers play it safe. They didn't seem to miss a beat with Mason running all over the Jets defense. The 49ers are likely going to draw this out all week, but fantasy managers who have McCaffrey rostered should get a backup plan ready for in case he does miss Week 2.
