49ers-Vikings injury report: Tramaine Brock listed as limited

The San Francisco 49ers and Minnesota Vikings got their practices going Thursday afternoon, and we have our first practice participation reports of the season. Teams do not have to release an injury report in the preseason, so we are left at the mercy of the coaching staff to reveal injury information. The injury reports are still somewhat vague in what they tell us, but the gamblers will take it!

The 49ers announced that cornerback Tramaine Brock was limited in practice with a hamstring injury. He dealt with the injury for the last couple weeks, sitting out some preseason action. Jim Tomsula said he was doing great, and did not expect him on the injury report, but obviously the 49ers are playing it safe in some regard. Tomsula seems to expect him to play, and I'm sure he'll get a question about that in his Saturday press conference.

Other than that, the 49ers had nobody on the injury report. They head into the game in good health, and more than likely all seven inactives will be healthy scratches. We like that.

The Vikings injury report is more about who is not listed than who is listed. Their injury report listed tight end Chase Ford, running back Zach Line and defensive tackle Shamar Stephen as limited participants. Tight end MyCole Pruitt was listed as a full participant. The bigger issue is center John Sullivan, who was placed on injured reserve with a return designation due to a back injury. Right tackle Phil Loadholt went on IR earlier in the preseason with a torn Achilles. That is a sizable chunk of their offensive line.
