Bradford's role in Saturday night's game at Cleveland will probably be similar to the opener, when he went 6 for 13 for 57 yards and was sacked four times in a 28-7 loss to the Vikings.
"It's just another opportunity to play in a game and get live reps," coach Steve Spagnuolo said Thursday. "I think at this position it's probably the most valuable thing you can get."
He'll also get his first look at a 3-4 defense.
"I think the more I can see that in the preseason the better it will prepare me to see that in the regular season," Bradford said. "There's a lot I can gain out of this week."
Feeley, a veteran backup, has played in the Rams' system previously. He had a poor opener, though, going 3 for 6 for 19 yards and two of the incompletions could have been intercepted and returned for touchdowns.
"I think what I'd say is he's a little bit more comfortable with [the offense], because he's been in it in prior years," Spagnuolo said of Feeley. "I think both of them are doing a pretty good job."
Bradford bobbled a few more snaps in practice Thursday, but said he felt much more comfortable. The rookie had some exchange issues in the preseason opener.
"Saturday I'll see what it's like in a game situation," Bradford said. "But I expect to go out there and execute everything cleanly."
The Rams managed only 150 total yards in their preseason opener and the lone touchdown came on Danny Amendola's 93-yard punt return.
Spagnuolo said offensive guard Jacob Bell and cornerbacks Ron Bartell and Bradley Fletcher, who all missed the preseason opener with injuries, should play. Kicker Josh Brown attempted field goals for the first time since injuring a hip flexor before a scrimmage Aug. 7, and might play.
Rookie tight end Michael Hoomanawanui left practice early due to illness.
