The San Francisco 49ers expect to get several key starters back for their Week 10 matchup against the Seattle Seahawks next Monday night. The team is holding a bonus practice on Tuesday, and three injured players were on the field at the start.

Tackle Joe Staley (fractured fibula) has already been practicing in a limited capacity and looked like he was preparing to get some work in during Tuesday's session. Returning to the practice field was the 49ers' other starting tackle, Mike McGlinchey (knee), and fullback Kyle Juszczyk (MCL sprain).

Tight end George Kittle, who suffered a leg injury last week against the Arizona Cardinals, did not practice. An MRI reportedly revealed no long-term damage for the Pro Bowl tight end.

Cornerback Ahkello Witherspoon (foot sprain), according to multiple reports, did not practice. Although, he was seen rehabbing his injury on a side field along with wide receiver Jalen Hurd.

Also absent from Tuesday's practice was tight end Levin Toilolo (groin).

The 49ers opened the practice window for tight end Garret Celek, who remains on the Reserve/Physically Unable to Perform list.

These notes are based on observations from reporters. The 49ers are not required to issue a practice participation report for Tuesday. The team has three more practices scheduled for this week.
