John Roveto's 26-yard field goal with 5:30 left in sudden-death overtime gave the Chicago Bears to a 20-17 victory over the San Diego Chargers today, ending a four-game losing streak.

The field goal was set up by an interception by safety Gary Fencik, who returned the ball 33 yards to the San Diego 26. The Bears (2-6) were set to try a 40-yard field goal, but the Chargers were penalized for being offside. Chicago moved the ball to the nine before Roveto's game-winning kick.

Roveto had missed two other field goals, one from 18 yards, and was not pleased by his performance.

"That's the worst I've ever played," said Roveto, acquired by Chicago three weeks ago after being cut by Dallas last year and Tampa Bay this season. "I would never have dreamed of missing those short ones."

The Chargers (5-3) had tied the game on a 39-yard touchdown pass from Dan Fouts to Wes Chandler with 1:40 left in regulation time, one minute after the Bears had driven 76 yards for a go-ahead touchdown on Walter Payton's two-yard run.

Payton had his best day of the season with 107 yards in 36 carries. It was his 43rd career 100-yard game, but only his first this season.

Fouts had 13 completions in 43 attempts for 295 yards. His first seven passes were incomplete, and he managed only three completions in 18 attempts for 72 yards in the first half. He was intercepted twice in the overtime period.

"I think we did an excellent job on him the whole game," said Fencik.

The Bears scored first on Matt Suhey's seven-yard touchdown run and Roveto's 31-yard field goal.
