Eagles center Cam Jurgens missed two games with a knee injury before returning Sunday against the Lions. He played 61 of 72 offensive plays before leaving with an undisclosed injury.
Jurgens didn't aggravate his knee injury.
Instead, Wednesday's practice report revealed Jurgens was diagnosed with a concussion.
He did not practice.
Brett Toth is Jurgens' backup.
Right tackle Lane Johnson (foot) also did not practice. He is expected to miss 4-6 weeks with a Lisfranc sprain.
Fred Johnson is Lane Johnson's backup.
Outside linebacker Jaelan Phillips (shoulder) was limited in Wednesday's practice, and offensive tackle Myles Hinton (back) and offensive lineman Willie Lampkin (knee/ankle) were full participants.
After working out multiple kickers, the 49ers have found their temporary replacement for Eddy Pineiro.
The team signed Matt Gay to the practice squad on Wednesday, cutting wide receiver Russell Gage Jr. from the practice squad in a corresponding move.
Pineiro has a Grade 1 hamstring strain, which prompted the kicker tryouts this week.
Gay, 31, was waived by the Commanders earlier this week.
He has made only 13 of 19 field goals, and he missed two field goals in Sunday’s overtime loss to the Dolphins. His 68.4 percent success rate ranks 32nd of the 34 kickers who have enough attempts to qualify this season.
Gay, a 2019 fifth-round pick of the Buccaneers, has also played for the Colts and Rams.
Rams place Quentin Lake, Tyler Higbee and Rob Havenstein on injured reserve

The Rams on Wednesday placed safety Quentin Lake, tight end Tyler Higbee and right tackle Rob Havenstein on injured reserve.
Lake, who had surgery Tuesday for a dislocated left elbow, Higbee (ankle) and Havenstein (knee/ankle) must sit out at least four games before they are eligible to return. The earliest return would be a Dec. 18 game against the Seahawks in Seattle.
“You don’t replace players like that,” McVay said of the experience and leadership that will be missing when the Rams play the Tampa Bay Buccaneers on Sunday at SoFi Stadium. “You can’t expect others to be able to do that. You expect guys that are getting opportunities to step up to be the best versions of themselves.”
Lake, 26, was injured last Sunday in a victory over the Seattle Seahawks, a win that improved the Rams' record to 8-2. McVay indicated that if Lake returns, it would possibly be for the playoffs.
Josh Wallace played in Lake’s place as a hybrid nickel corner/linebacker. McVay said the Rams would continue to evaluate and formulate a plan to replace Lake moving forward, but they are expected to consider utilizing a combination that includes safety Kam Kinchens, Wallace and cornerbacks Cobie Durant and Roger McCreary.
The 10th-year pro has 20 receptions, including two for touchdowns, as the leader of a tight end group that includes Davis Allen, Colby Parkinson and rookie Terrance Ferguson, who is expected to get an increased role in Higbee’s absence.
Havenstein, an 11th year pro, played the first four games before he was sidelined for three games because of injuries. Third-year pro Warren McClendon played in his place.
Havenstein returned against the New Orleans Saints and has played the last three games, but McVay said time on injured reserve would enable him to work back to full strength.
“Both of those guys are obviously big-time leaders and catalysts on our team and our offense,” quarterback Matthew Stafford said of Higbee and Havenstein. “But we’ll just move forward with the guys that we have, and then hopefully those guys can heal up and be ready to go at some point.”
In corresponding moves, the Rams signed kicker Harrison Mevis to the active roster, claimed safety Chris Smith II off waivers from the Las Vegas Raiders and signed cornerback Alex Johnson to the practice squad.
