Quarterback J.P. Losman will start his second straight game when the Buffalo Bills host the Carolina Panthers Sunday. Coach Mike Mularkey said he's encouraged with the progress Losman has shown in the last two games since taking over for an injured Kelly Holcomb. "After watching the tape, I thought J.P. performed pretty well," Mularkey said, referring to Losman's 20-of-36 for 168 yards passing with a touchdown and interception in a 48-10 loss at San Diego on Sunday.
