Oakland Raiders tight end Kevin Boss has been listed as week-to-week with a sprained left knee.
Boss was injured in Saturday's preseason game against San Francisco when he took a helmet to the knee.
He was signed to a four-year, $16 million contract earlier this month.
The 6-6, 250-pound Boss caught 119 passes for 1,600 yards and 18 TDs in four years with the New York Giants, including 35 receptions for 522 yards and five TDs last season.
