Donte Jackson enters concussion protocol after head injury against Bills

Chargers cornerback Donte Jackson has entered the concussion protocol following a head injury sustained during Sunday's game against the Bills. Jackson exited the contest in the first half and was ruled out for the remainder of the game. He was initially listed as questionable to return. Rodney Shelley replaced him on the field. Jackson, in his second season with the Chargers, has made seven tackles, one tackle for loss, and two passes defended in the first three games of the season. The duration of his time in protocol remains uncertain, and Cam Hart and Tarheeb Still are expected to take on larger roles in the upcoming game against the Seahawks.
