BOSTON (CBS) — After a long time away due to a calf injury, offensive tackle Trent Brown has returned to the practice field for the Patriots.

Brown suffered the injury in the first quarter in the first game of the season, eventually leading to a trip on injured reserve. But he was on the practice field on Wednesday, starting his 21-day clock to be added to the active roster.

It wasn’t much of a positive day on the attendance front outside of Brown, though, as five players were absent.

Matthew Judon was absent, but he announced on Instagram that his wife was having a baby this week.

Damien Harris, Rhamondre Stevenson and Gunner Olszewski — all of whom suffered concussions during Sunday’s win — were all absent from practice.

Additionally, linebacker Jamie Collins was absent on Wednesday, sidelined with an ankle injury.

Another nine players were limited on Wednesday. Here is New England’s full injury report from Wednesday:

DID NOT PARTICIPATE
LB Jamie Collins, Ankle
RB Damien Harris, Concussion
LB Matthew Judon, Not Injury Related
WR Gunner Olszewski, Concussion
RB Rhamondre Stevenson, Concussion

LIMITED AVAILABILITY
P Jake Bailey, Right Knee
LB Ja’Whaun Bentley, Ribs
K Nick Folk, Left Knee
WR N’Keal Harry, Knee
LB Dont’a Hightower, Ankle
G Shaq Mason, Abdomen
CB Jalen Mills, Thigh
TE Jonnu Smith, Shoulder
LB Kyle Van Noy, Groin

The Browns are dealing with issues of their own this week, with several players — including their top two running backs — testing positive for COVID-19, in addition to a number of players missing practice due to injury on Wednesday.

The Patriots host the Browns on Sunday at 1 p.m. Certainly, both teams will have some roster work to do before that game begins.
