One day after reaching the NFL's mandatory 53-man limit, the Bears on Wednesday made several moves that involved their active roster:

• They re-signed cornerback Artie Burns and safety Marqui Christian, two veterans who were released Tuesday.

• They placed linebacker Danny Trevathan and rookie tackle Teven Jenkins on injured reserve, meaning that they will miss at least the first three games of the season.

Speaking to the media Wednesday, Bears general manager Ryan Pace indicated that Trevathan's knee was bothersome during training camp and seemed hopeful that his stint on injured reserve would be a short one.

"Our plan, especially with these IR rules being pretty flexible for us, is to go ahead and get him on there and let him kind of take his time," Pace said. "Make sure he's 100 percent before we put him out there. We're just kind of working through that. Make sure we get him 100 percent. It's what is best for him. It's what is best for us."

The Bears remain hopeful that Jenkins will be able to return sometime this season after recovering from recent back surgery. Pace said that the second-round pick arrived at training camp experiencing different symptoms than he ever had at Oklahoma State.

• They claimed receiver Nsimba Webster off waivers from the 49ers. Webster entered the NFL with the Rams in 2019 as an undrafted free agent from Eastern Washington. He appeared in 21 games the past two seasons, primarily on special teams, averaging 6.3 yards on 32 punt returns and 22.4 yards on 18 kickoff returns. The 5-10, 180-pounder played just eight snaps on offense and had no receptions.

Webster was waived by the Rams July 21 and claimed by the 49ers. He was then waived by the 49ers Tuesday as part of final cuts.

Pace described Webster as "not only a good returner, but also a really good full core special team player. He's a really good gunner, he's really good on kickoff coverage."

• They waived receiver Rodney Adams.
