McDonald (hamstring) will not play against the 49ers on Sunday.
McDonald was able to return to practice after sitting out on Wednesday, but will be held out due to the lingering nature of hamstring injuries. However, he appears to have an optimistic chance of returning next week. Akeem Spence will get the start on Sunday as his replacement.
James (undisclosed) reached an injury settlement with the Buccaneers on Wednesday, ESPN reports.
Following a three-year stint with the Bucs, the team decided to part ways with James due to a vague injury he can't seem to overcome. In the wake of his release, Tampa Bay promoted rookie Peyton Barber from the practice squad and plucked Jacquizz Rodgers off the free agent market.
Bell (concussion) reached an injury settlement with the Buccaneers on Thursday, Aaron Wilson of the Houston Chronicle reports.
Bell suffered a concussion in Week 4's preseason finale against the Redskins, leaving him on the sidelines for an extended amount of time. The team decided to part ways with wideout instead of holding him on IR for the year.
Dorsey (knee) is inactive for Sunday's matchup against the Buccaneers.
Dorsey has been hindered by a knee injury since the preseason that has caused him to miss Week 5 and now Week 7. With Dorsey out, look for starting nose tackle Mike Purcell to see even more action than usual.
Hyde (shoulder) is inactive for Sunday's Week 7 tilt versus the Bucs, the team's official site reports.
As expected, the bell-cow back will take a set with his shoulder injury, while a combination of Mike Davis, Shaun Draughn and DuJuan Harris set to handle the backfield workload against a tough Bucs run defense.
Robinson is out for the rest of Sunday's game with a knee injury.
Robinson is merely a depth provider in the defensive backfield, so his absence shouldn't greatly affect the 49ers' performance for the rest of Sunday's game. More will be known regarding the severity of his injury in the near future.
Smelter (hamstring) was added to the 49ers' practice squad, Matt Maiocco of CSN Bay Area reports.
Smelter was cut by the 49ers prior to the season after suffering a hamstring injury during training camp. Prior to the injury, the 2015 fourth-round pick had light breakout potential due to his size and athleticism. It is unclear if and when the 49ers will give Smelter a chance on the 53-man roster, or even if his hamstring injury has fully healed. While he is definitely not a player worth picking up right now, there is still potential for a late-season appearance where the team tries to get a better look at their former top receiving prospect on a team devoid of reliable options at that position.
