Las Vegas Raiders tight end Darren Waller continues to struggle in his attempt to return from a knee injury.
Per ESPN's Jeremy Fowler, Waller isn't expected back for Saturday's game against the Cleveland Browns.
If Waller is unable to play, this will mark his third straight game missed. He originally injured his knee in the Raiders' 36-33 overtime victory over the Dallas Cowboys on Thanksgiving.
Waller has already missed three games this season. He sat out a Week 7 contest against the Philadelphia Eagles with an ankle injury.
Upon returning after the bye in Week 8, Waller caught 20 passes for 265 yards over the next four games.
