Defensive end Jason Taylor was on crutches Monday because of a foot injury, leaving his status for Sunday's game against Kansas City uncertain. Taylor was hurt during the first quarter of yesterday's 27-13 loss at Tampa Bay. He returned to the game but said he was slowed by the injury. The Dolphins didn't disclose the nature of the injury, but coach Nick Saban said Taylor's foot is swollen. Saban said trainers will keep Taylor off the foot for a couple days and evaluate his status later in the week.
