SANTA CLARA, Calif. (AP) _ All-Pro receiver Terrell Owens will skip the San Francisco 49ers' voluntary passing camp this week for undisclosed personal reasons.

Owens, who has made the last three Pro Bowls, didn't tell new coach Dennis Erickson why he couldn't make it to the workouts, which began Wednesday. The camp, which concentrates on the Niners' offense, ends Friday.

Erickson said he isn't worried about his star falling behind the learning curve as the new coaching staff installs its variations on former coach Steve Mariucci's offense. The 49ers' final full minicamp begins on Monday.

``He was here for the first minicamp, so a lot of it is pretty much the same,'' Erickson said. ``It won't be very difficult for him. ... Hopefully, he'll be here next week.''

Owens attended the 49ers' first minicamp four weeks ago, but he didn't participate while resting his sore legs. He hadn't completely healed from the regular season, when he caught 100 passes for 1,300 yards and 13 touchdowns despite constant nagging injuries.

Owens is entering the final year of his contract, but the 49ers hope to sign him to a new deal before the regular season begins.

Left tackle Derrick Deese also missed the start of the camp with a leg injury.
