The 49ers have ruled LB Dre Greenlaw (calf) out for Sunday's game against the Seahawks. Azeez Al-Shaair looks like his playing-time replacement. No other Niners LB behind Al-Shaair, Greenlaw and Fred Warner has played more than 28 snaps on the season.

Niners LB Dre Greenlaw left Sunday's win over the Raiders with a back injury. HC Kyle Shanahan said Greenlaw would have a Monday MRI to determine the extent.

Officials ejected 49ers LB Dre Greenlaw late in the 2nd quarter of Sunday night's game against the Chargers after a hit to the head of Chargers QB Justin Herbert. We wouldn't bet on any league suspension accompanying this, so Greenlaw should be set to return next Monday night at Arizona.

Niners LB Dre Greenlaw (calf) has been cleared to play Sunday night against the Chargers. Greenlaw hasn't played since Week 7, so it's tough to know if he's ready for a full snap allotment. But he'll carry upside if he does. The Chargers have supplied the 5th most fantasy points per game to LBs so far this season.

The 49ers got LB Dre Greenlaw (calf) back for a limited practice Wednesday. He missed the last game (Week 8) with the injury that knocked him out of the loss to the Chiefs. We'll watch to see whether he's ready to return to the lineup this Sunday against the Chargers. DL Arik Armstead (foot, ankle) remained out Wednesday, which doesn't bode well for his chances of playing for the 1st time since Week 4. EDGE Samson Ebukam (quad, Achilles') also didn't practice.

The 49ers have ruled LB Dre Greenlaw (calf) and DL Arik Armstead (foot, ankle) out for Sunday's game against the Rams. Demetrius Flannigan-Fowles looks like the fill-in for Greenlaw. Armstead will be missing his 4th straight game.
