Trenton Cannon left Sunday's game between the San Francisco 49ers and Seattle Seahawks in an ambulance. The 49ers running back suffered a concussion on a vicious hit from a Seahawks player on the opening kickoff, and was transported to a local hospital where he spent the night for observation.
On Monday, a day after the game, head coach Kyle Shanahan spoke with reporters via a conference call and provided an update on Cannon.
"Trenton Cannon, he's in the concussion protocol," Shanahan said. "He's doing better. He's been discharged from the hospital, and he's flying home right now. Our doctors will continue to monitor him."
Shanahan also provided several other injury updates from the team's defeat at Lumen Field. The most significant loss is cornerback Emmanuel Moseley, who will miss "several weeks" with a high-ankle sprain.
Running back Elijah Mitchell is also in the concussion protocol.
"He was cleared after being evaluated during the game and post-game, but he had symptoms this morning, so he's in the concussion protocol," Shanahan said.
Running back Jeff Wilson's knee flared up during the game.
"He's expected to be back in practice this week," Shanahan noted. "... When people come back from a big injury ... people have things flare up, and that's happened with Jeff a couple of times. It happened a little bit in the game, and that's why he was struggling a little bit. But that's why he wasn't taken out either. He was there in case of an emergency, and I know he's doing a little bit better today. Like it has been I'm sure it will get better each day as we go here."
Shanahan added that he didn't receive any reports on safety Jaquiski Tartt's hamstring, so the coach assumes the defender is fine.
As for a couple of 49ers stars who did not play on Sunday—wide receiver Deebo Samuel and linebacker Fred Warner—their statuses remain uncertain.
"It's still early on Monday," Shanahan said. "Fred was closer than Deebo was last week, so I expect to get Fred back at practice this Wednesday. Deebo, we'll go day-to-day with him. I'm hoping to get him back this week, but it's still too early to tell."
