Philip Rivers threw for 377 yards and three touchdowns, two to Eddie Royal, and the San Diego Chargers turned back an early scare from Blake Bortles and the winless Jacksonville Jaguars for a 33-14 victory Sunday.

Royal had scoring catches of 47 and 43 yards, his second straight two-touchdown game. The Chargers (3-1) extended their winning streak to three.

Passing because the Chargers' running game is nonexistent due to injuries to Ryan Mathews and Danny Woodhead, Rivers had his second three-touchdown game of the season. He went 29 of 39.

Royal had five catches for 105 yards. Keenan Allen had 10 for 135, both career highs, and Malcom Floyd had a 24-yard touchdown catch.

Bortles made his first start for the Jaguars (0-4), threw one touchdown pass, was intercepted twice and twice had Jacksonville in the lead in the first half.
