Bradford participated on a limited basis during Friday's practice, but he went through some 7-on-7 drills.
"He's as questionable as you can be," Rams coach Steve Spagnuolo said. "He was limited in practice. Some things we kept him out of, some things we let him go. Now the deal is let's see how it is tomorrow after he's done a little more work. We'll take it one day at a time and see where we're at on Sunday."
"I'm sure that's coming," Spagnuolo said. "He's a competitor. We'll see where we're at."
Bradford declined to speak to reporters after practice.
