The San Francisco 49ers and Kansas City Chiefs each released their first practice participation reports of the week. They will release a second report Thursday, and then a final injury report on Friday. There are no big shocks in the report, but a few items of note for each team.
Vernon Davis and Anthony Davis both sat out Wednesday's practice. They both returned to action last Sunday, only to suffer injuries during the game. Vernon suffered a back injury and has said he is day-to-day. He did say his back still aches when he sits down or stands up. Anthony suffered a knee injury, and had an MRI earlier in the week. He was spotted walking through the locker room on Wednesday with no brace, and no noticeable limp.
Tramaine Brock continues to sit out practice, but it sounds like he is making some progress. According to Matt Maiocco, Brock has officially begun on-field rehabilitation. He probably will not play this weekend, but he is getting a little bit closer.
On the Chiefs side of things, fourth round pick De'Anthony Thomas was a full participant in practice. The speedy Oregon running back has yet to make his NFL debut. If he is active this weekend, there is a very good chance he will be the team's primary kick and punt return option.
Wide receiver Donnie Avery sat out practice. He left Monday's win over the Patriots with a groin injury that is now being described as an abductor strain. If he is unable to go this Sunday, A.J. Jenkins could find himself getting a little more playing time. The 49ers former first round pick has four receptions for 16 yards this season. Dwayne Bowe is the Chiefs "No. 1 wide receiver", but Travis Kelce has been Alex Smith's top target, just ahead of Avery. And of course, Jamaal Charles is a guy who can be very active in the passing game. Jenkins will get some snaps, but he will still be a good ways down the target depth chart.
