The Chargers weren’t as troubled as they might have been by the season-ending knee injury to linebacker Shawne Merriman because the team is very high on his replacement, Jyles Tucker.

They might now have to make it without Tucker, at least for this week.

Tucker hasn’t practiced on Wednesday or Thursday due to a hamstring injury.  It’s unknown at this point whether he’ll play on Sunday when the Chargers travel to Miami.
