McManus did not attempt a field goal and went 5-for-5 on extra-point tries during Sunday's 35-21 win over the Raiders.
McManus signed with Los Angeles this week after Blake Grupe (knee) was placed on injured reserve. The kicker wasn't tested too much Sunday, but he was able to avoid making any mistakes. McManus will have a chance to attempt his first field goal as a member of the Rams in Week 8 against the Chargers.
