San Francisco 49ers wide receivers Deebo Samuel and Jauan Jennings and tight end George Kittle all missed practice on Wednesday.

Samuel was just released from the hospital on Tuesday with pneumonia-like symptoms, but he could still play this week, 49ers coach Kyle Shanahan told reporters Wednesday. Jennings (hip) also missed last week’s game against the Kansas City Chiefs while Kittle (foot) did play.

The team also announced earlier this week that WR Brandon Aiyuk is done for the season after tearing his ACL and MCL in Sunday’s loss.

The Niners (3-4) host the Dallas Cowboys (3-3) on Sunday night.

Samuel was in on just four plays against the Chiefs, never touching the ball, before being ruled out since he was having trouble breathing, according to Shanahan. Samuel, 28, has 20 catches for 335 yards and one touchdown this season. He also has 19 carries for 51 yards and a score.

Jennings didn’t practice at all last week. He leads San Francisco with 404 receiving yards. He also has 25 receptions and three touchdowns.

Kittle leads the team with 34 receptions and has 375 yards with five TD catches. He’s considered day-to-day.
