SANTA CLARA –- Despite a right hand injury that landed him on the 49ers’ injury report on Wednesday, quarterback Colin Kaepernick’s status is a thumbs-up for Sunday’s game against the St. Louis Rams.

Kaepernick sustained a swollen thumb on his throwing hand in the 49ers’ 20-3 loss to the Seattle Seahawks on Thursday. X-rays revealed no fracture, he said, and he was able to participate in the team’s full practice on Wednesday.

Linebacker NaVorro Bowman and running back Carlos Hyde were held out of practice. Bowman, who is nursing a shoulder injury, has not practiced on a Wednesday since the start of the regular season.

Hyde has a stress fracture in his left foot and is not likely to practice during the week until the condition improves.

Linebacker Ahmad Brooks (shoulder) and safety Eric Reid (chest) wore blue practice jerseys, signifying they were off-limits for contact. Both players, along with offensive linemen Alex Boone (shoulder/knee) and Joe Staley (shoulder) took part in limited practice.
