Bartell's objective is to make the arrangement permanent.
"I'm definitely looking to keep it," Bartell said Monday. "I'm not trying to give it back. I just want to go in and play my best and just let the chips fall where they may."
Bartell, a second-round pick in 2005, tied for the team lead with three interceptions last year, despite only one start. Because of injuries he was able to start seven games his rookie season.
Linehan had no complaints with Bartell's play against the Vikings, noting he rebounded well after early struggles in coverage. Bartell was part of a unit that held Minnesota to 215 total yards and three points on offense.
"I don't think the game was one of his better games, but it wasn't awful," Linehan said. "He recovered and played very good when he played the last couple of drives, made a couple of nice plays and a couple of real nice tackles.
"I think that's what you've got to go through with a young corner."
Two of Bartell's interceptions last year came in the season finale against the Vikings, and he returned one for a touchdown. He's hoping to build on that momentum while Brown, whose suspension is scheduled to begin on Aug. 31, watches in street clothes.
"I don't think I look at it like it's an audition," Bartell said. "I just look at it like it's an opportunity.
"I just need to step my game up along with some other guys."
Bartell also has experience at safety, increasing his value to the team.
"I've got to put in a lot more studying time than some people," Bartell said. "I'm up for the challenge. The more you can do, the more important you are, that's how I look at it."
Notes: Linehan also has been happy with the play of rookie CB Jonathan Wade, a third-round pick, and free agent pickup Lenny Walls. ... The Rams reopened training camp to fans on Monday and got a huge break from a heat wave that had temperatures at or near triple digits for about a week. It was down to the upper 70s after an overnight storm, and Linehan expects practices to be outside all week. ... DT La'Roi Glover (hip flexor) was held out of practice but could return on a limited basis as early as Tuesday. ... The competition at C continues this week with Andy McCollum, who sustained a season-ending knee injury in last year's opener, starting ahead of Brett Romberg, who started in the preseason opener.
