Vikings cornerback Trae Waynes was ruled out Saturday for Monday’s game at Seattle while linebacker Eric Kendricks was listed as questionable. Kendricks had missed practices Thursday and Friday with a rib injury before returning Saturday. Waynes didn’t practice all week after suffering a concussion in the second quarter of last Sunday’s 24-10 loss at New England. Also ruled out for Monday were tight end David Morgan (knee), who will miss his fourth straight game, and wide receiver Chad Beebe (hamstring), who will miss his third in a row. Vikings coach Mike Zimmer said Kendricks should be “fine” on Monday, an indication he likely will play.
