Jimmie Ward has a Grade 1 quad strain and could miss 1-2 weeks

49ers head coach Kyle Shanahan provided injury updates this afternoon on a conference call. Running back, Elijah Mitchell is dealing with a rib injury and will be limited in practice Wednesday. Jimmie Ward has a Grade 1 quad strain and has an “outside chance” of playing this week, but he’s “not really optimistic.” Shanahan said it’s more likely Ward is out 1-2 weeks. Tavon Wilson will start in his place.

Speaking of safeties, Kai Nacua has a hamstring injury and will miss three weeks. Nacua is a reserve, but without Ward and Tartt, Talanoa Hufanga and Wilson are the lone safeties that are healthy.

JaMycal Hasty and Trey Sermon will fill in for Mitchell if he cannot play. Jeff Wilson Jr. will return to practice as the 49ers will open his practice window, though there’s no guarantee Wilson Jr. plays Sunday.

Wilson Jr. has been out of football for a few months. So I wouldn’t expect him on the active roster for at least a couple of weeks.

Deebo Samuel (calf) and Trent Williams (ankle) will be limited this week. That was the case for Williams last week. The expectation is that both players play in Week 9.

The team will also open the practice window for George Kittle (calf) and Robbie Gould. Shanahan is optimistic that DE Dee Ford and LB Azeez Al-Shaair will return from concussions this week against Arizona. Each player should suit up Sunday.

Shanahan said he would be surprised if the 49ers make a trade by tomorrow’s deadline. They are open to making a move that can help them immediately but doesn’t want to do anything that hurts them in the future.

That question came as he commented on Von Miller being traded to the Rams: That’s going to help them right now, that’s for sure.” Sean McVay said the same last month, and the team still landed Miller.

Shanahan said health concerns, wanting to ease him back after injury was the main reason Trey Lance didn’t play this week: “I wasn’t just going to throw him out for there for [situational plays].”

Jimmy Garoppolo’s second rushing touchdown came on a designed run. I wonder if that play goes to Lance if Shanahan feels the rookie is healthy enough.

Shanahan is “hoping” Dre Greenlaw returns to practice Wednesday, but he’s “still not sure” as Greenlaw must pass some additional tests. Greenlaw has a core muscle injury. Assuming Al-Shaair returns, the team doesn’t have to rush Greenlaw back.

Shanahan asked general manager John Lynch to speak to the team on Saturday night. Shanahan said he thought it would be great for the team to hear a different perspective from the Hall of Famer: “He fired us up and gave the players a lot of perspective. ... It was even better than expected.”
