Taylor Hart is headed back to Philadelphia.
Just two days after the 49ers waived the defensive tackle, the Eagles claimed him on Monday. Philadelphia announced the Hart acquistion in a series of roster moves.
The 49ers originally got Hart when they claimed him off waivers from the Eagles on Sept. 5.
Hart was waived on Saturday when the 49ers promoted running back DuJuan Harris to the active roster.
The Eagles' 2014 fifth-round pick appeared in one game for the 49ers and made two tackles.
SANTA CLARA – Cornerback Rashard Robinson and outside linebacker Aaron Lynch might not be available when the 49ers return after the bye week to play the New Orleans Saints on Nov. 6.
Neither Robinson nor Lynch sustained long-term injury, 49ers coach Chip Kelly said on Monday, a day after they left the game in the third quarter of the 49ers’ 34-17 loss to the Tampa Bay Buccaneers. Both players underwent MRI examinations on Monday.
Robinson sustained a partially torn MCL in his left knee. The injury will not require surgery, but it is uncertain how long he will be out of action. Lynch sustained a high left ankle sprain. He is also questionable for the 49ers’ next game.
The 49ers players had meetings on Monday before Kelly dismissed the team until next Tuesday.
Defensive lineman Arik Armstead also left Sunday’s game due to an injury in the third quarter. Kelly suggested Armstead’s shoulder condition will not prevent him from being ready to play upon the team’s return to action.
