LOS ANGELES _ An open date last week gave the Rams plenty of time to heal and prepare for the Carolina Panthers.
The defense appeared to benefit.
The offense did not.
Case Keenum and the offense were booed several times and fans at the Coliseum called for rookie quarterback Jared Goff in a 13-10 loss that extended the Rams losing streak to four games and dropped their record to 3-5.
A week after complaining that officials were not calling penalties for illegal hits against him in the pocket, Newton completed 20 of 32 passes for 225 yards and a touchdown as the Panthers improved to 3-5.
Keenum completed 27 of 46 passes for 296 yards and a touchdown, with an interception.
Rams running back Todd Gurley rushed for 48 yards in 12 carries.
The Panthers led, 7-0, at halftime on Newton's touchdown pass to tight end Greg Olsen and then added a third-quarter field goal by Graham Gano.
The Rams had a chance to score a touchdown midway through the fourth quarter, but tight end Lance Kendricks dropped a seven-yard pass at the goal line, forcing the Rams to settle for a field goal.
Gano added a field goal with 3:18 left for a 10-point lead, but Keenum's short touchdown pass to Kenny Britt with 34 seconds remaining helped cut the deficit to three points.
The Panthers recovered a squib kick to secure the victory.
The Rams had first-half scoring opportunities.
When their opening drive stalled at the Panthers' 37-yard-line, Greg Zuerlein came on and missed a 55-yard field goal attempt. It was Zuerlein's first miss after making all 10 of his previous attempts this season.
The Panthers began their only scoring drive with nine minutes left in the first quarter.
Newton completed passes to Ted Ginn Jr., tight end Ed Dickson and receiver Kelvin Benjamin and then picked up a first down on a designed run. On third and five from the nine, he connected with Olsen for a touchdown and a 7-0 lead.
The Rams defense and punter Johnny Hekker did their part for the rest of the half, and the Panthers' opportunity to extend the lead failed when Gano missed a 48-yard field goal attempt with 29 seconds left.
Keenum connected with Britt and Brian Quick to move the Rams across midfield, but another 55-yard field-goal attempt by Zuerlein again went wide right.
