49ers’ George Kittle still not practicing; Trey Lance awoke with ‘sore neck’

SANTA CLARA — Here is what we’re learning at 49ers headquarters Wednesday, ahead of practice for Sunday’s home opener against the Seattle Seahawks:

STILL NO KITTLE

Tight end George Kittle remains out of practice because of a groin injury, which kept him out of Sunday’s season-opening loss. He sustained the injury Sept. 5. “He’s made a lot of progress so hopefully we’ll have better luck this week,” coach Kyle Shanahan said.

DEFENSIVE END TO IR

Defensive end Jordan Willis requires a “clean-up procedure” on a chornic knee issue and will go on injured reserve. Willis did not suit up in Sunday’s opener and was not on an injury report leading up to the game, but he’s since reported how pain flared up and underwent an MRI this week.

In a corresponding roster move, defensive end Kemoko Turay is being promoted from the practice squad.

LANCE’S SORE NECK

Quarterback Trey Lance acknowledged some neck soreness the day after the opener, in which he had 13 carries and endured two sacks.

“I felt fine. My neck, honestly, was a little sore,” Lance said. “That was the first thing, because I don’t get hit at all throughout the year. So other guys get to build up and get their necks ready for the season. Other than that, I feel good.”
