"It wasn't a high-ankle sprain," Shanahan told reporters on Wednesday, "so we're very fortunate that he'll play again for us this season. But it's not healthy enough to go (in practice) today. I'm holding out hope for it this week, but it will be a day-to-day thing."
Jones suffered the ankle injury during the first half of Monday night's 34-24 loss to the Buffalo Bills, was listed as "questionable" to return, and then downgraded to "out."
Jones has 14 tackles, six tackles for a loss, two sacks, and a pass defensed through 11 games this season. He landed on injured reserve last season due to a high-ankle sprain suffered that December.
Shanahan also noted that the following players would not practice on Wednesday.
- OL Tom Compton is in the concussion protocol.
- WR Deebo Samuel is dealing with a foot contusion, could practice later in the week.
- CB K'Waun Williams is still dealing with his ankle injury. Shanahan said the team would see how he progresses this week.
- CB Emmanuel Moseley is still dealing with a hamstring injury.
- DL Kevin Givens is excused for personal reasons.
