According to ESPN Boston's Mike Reiss, the New England Patriots have promoted linebacker Darius Fleming from their practice squad to the 53-man active roster. Fleming, who was drafted in the 5th round of the 2012 NFL Draft by the San Francisco 49ers, is with the Patriots since May.
Fleming's promotion likely means two things:
1) Backup linebacker and core special teamer Chris White probably won't play in Sunday's game against the Green Bay Packers (and might also miss the Patriots' week 14 game on the road against the San Diego Chargers). White was listed as "questionable" on Friday's injury report with an ankle injury. He did practice fully on Wednesday, was limited on Thursday, and missed Friday's session altogether.
2) Defensive tackle Sealver Siliga won't be promoted to the active roster yet. Siliga, who was placed on injured reserve with a designation to return after suffering a foot injury in week 3, started practicing again this week. After his first practice on Friday, the Patriots' 21 day window to activate him has opened. They will probably wait until after their game in San Diego to do so.
The Patriots have had an open roster spot after waiving safety Don Jones on Thursday.
