Brown signed with the Rams' practice squad Tuesday.
Brown has had multiple stints in Los Angeles, most recently spending training camp with the team before being waived in August. However, he's never kicked in an NFL regular-season game. That could change in Week 3 due to Joshua Karty dealing with a groin injury; however, the rookie kicker is expected to be fine for Sunday's game against the 49ers. If Karty were to suffer a setback, though, Brown would likely be elevated to handle the job.
