According to the Press-Gazette, Mike McCarthy discussed the following injuries from the Green Bay Packers game against the Bears.
RT Bryan Bulaga suffered a knee sprain and bruise. It's not serious, but they'll have to see how his recovery goes this week. I'm expecting he'll miss a game or two, similar to the recent shoulder bruise suffered by CB Tramon Williams.
RB Ryan Grant had a kidney bruise and he'll be reevaluated later this week. I've got no idea about this one, or if it will keep him out at all. Too bad for Grant, who had his best game of the season on Sunday. He'd been outplayed by James Starks in their first two games.
LB Brad Jones had a hamstring strain. He's playing mostly on special teams, but shows up on defense from time-to-time, though he only has 4 tackles on the season. Since he finished the game with the injury, it sounds like he'll be available next Sunday.
