NAPA, Calif. -- Chaz Schilens, who's projected to be one of the Oakland Raiders' top two receivers this season, broke a bone in his left foot while running a route during Tuesday's joint practice with the San Francisco 49ers.
Raiders coach Tom Cable didn't provide a timeline for when Schilens might return, but such an injury likely would sideline Schilens for at least a month. He has been a major bright spot in the receiving corps this training camp.
Schilens said he didn't know whether he would need a cast or walking boot on the foot. He also didn't rule out playing in the team's season opener Sept. 14 against the AFC West rival San Diego Chargers.
"If God works a miracle, we'll see," he said.
Schilens said he was uncovered when he made a cut and felt a sharp pain in his foot. X-rays revealed he had broke the fifth metatarsal in his foot, and he left after practice on crutches.
"I couldn't run anymore, so I knew something was wrong," Schilens said.
Schilens, 23, made six starts for the Raiders during his rookie season in 2008, finishing with 15 catches for 226 yards and two touchdowns. He was a seventh-round draft pick last year out of San Diego State.
"It's pretty frustrating, but you know we have good receivers, good young receivers," Schilens said. "I'll support those guys and help them any way I can and try to hurry up and get back out here as fast as I can. I can't focus on the negative. I've got to just look for the healing process right now and move forward."
With Schilens out, the Raiders' receiving corps is in limbo and the depth gone.
Javon Walker hasn't practiced at all this camp while recovering from offseason knee surgery. Cable said he expects Walker to join Oakland's workouts Monday but declined to say when or if the veteran would be able to play this preseason.
In addition, first-round pick Darrius Heyward-Bey continues to have problems catching the ball. He had three drops during the joint workout Tuesday.
