Cardinals WR Anquan Boldin aggravated a right-ankle sprain in the third quarter Sunday on the 537th reception of his career, an 8-yard gain. He hobbled off the field and didn't return.
Boldin has played the past two games despite the sprain, but his availability for Sunday's game at Chicago is in question.
"The one issue we had going into the game was if he took a shot on that ankle," coach Ken Whisenhunt said. "As low of probability of that happening, it did happen. It's hard when you lose him in the game, because you only have so many receivers that are active. That's what makes it difficult."
