Cardinals WR Anquan Boldin was limited again in practice Friday, and his availability for Sunday's game against the 49ers likely won't be determined until pre-game warmups.
"It's improving every day," Boldin said of his right hamstring injury.
Boldin said he did some sprinting on Friday but didn't try to push himself too hard. "I think I've worked hard enough during the week to get to this point. I don't want to do anything at this juncture to set it back."
Boldin hasn't practiced fully since suffering the injury on Aug. 25. Over the last two days, he's gone over his assignments in the lighter part of practice, but admitted he faces a difficult decision.
