The 49ers have signed veteran wide receiver Louis Murphy, according to his reps at Universal Sports Management (Twitter link). Murphy was with the Niners over the summer but missed the pre-Week 1 cut when he was released in early September. 
Murphy has spent time with four clubs during his pro tenure, with his last stop coming in Tampa Bay. The 30-year-old’s best season came in 2010, when he posted 41 receptions and 609 yards for the Raiders. Unfortunately, he’s been held back by injuries and off-field issues ever since. In 2015, he tore his ACL and suffered a setback while trying to rehab the injury. He also was arrested on gun charges earlier this year.
The veteran will help to provide depth for San Francisco following Pierre Garcon‘s season-ending injury.
