Broncos, Chargers injury update

Posted by ESPN.com's Bill Williamson

Injury report from Denver and San Diego:

In Denver, defensive end John Engelberger practiced fully for the first time this week. He has been hampered by a knee injury but he is expected to play Sunday against Tampa Bay.

Backup defensive tackle Josh Shaw is out with a groin injury. Backup receiver Darrell Jackson, who has missed the past three games with a calf injury, has been limited all week and is listed as questionable on the injury report.

In San Diego, linebacker Jyles Tucker, Shawne Merriman's replacement, is doubtful to play at Miami on Sunday with a hamstring injury. Marques Harris is set to replace him.

There are no other major injury concerns in San Diego. Running back LaDainian Tomlinson is off the injury report this week for the first time since he suffered a turf toe injury in Week 1 against Carolina.
