ENGLEWOOD, Colo. (AP) Mark Sanchez will miss the first few days of OTAs next week after undergoing surgery to repair a ligament in his left, non-throwing hand.

The Denver Broncos' new quarterback injured his left thumb in a weight room mishap on Thursday while participating in team-wide strength and conditioning work.

He underwent surgery Saturday in Vail, Colorado.

With Sanchez expected to miss seven to 10 days, second-year pro Trevor Siemian and first-round draft pick Paxton Lynch will be taking the snaps when organized team activities begin May 24.

Sanchez, a seven-year pro acquired in a trade with Philadelphia earlier this offseason, is expected to return to action the following week.
