The Las Vegas Raiders were without tight end Darren Waller for most of Monday night’s 30-29 loss to the rival Kansas City Chiefs. Waller was ruled out with a hamstring injury Monday night after just six plays against Kansas City. He left the field early in the first half and returned to the sideline to open the second in street clothes.

Head coach Josh McDaniels told reporters in his postgame news conference that he does not believe Waller’s injury is “super significant.”

The former Pro Bowler’s evening ended with no catches, no targets and five routes run on those six snaps. His final snap was on a fourth-and-1 play in the first quarter that resulted in a Derek Carr-to-Davante Adams 58-yard touchdown pass.
