Injured Garcia sticks to light drills in camp

SANTA CLARA, Calif. (AP) -- Jeff Garcia won't be able to show off his arm strength until his back gets a little stronger.
Garcia stuck to short throws and easy drills in the first workouts of the San Francisco 49ers' training camp. The three-time Pro Bowl quarterback hurt his back during a workout with a personal trainer last Monday, and he won't be ready for extensive workouts until next week.
Garcia is never comfortable on the sidelines, and he fidgeted with extra intensity on Friday. He believes new coach Dennis Erickson's offense will allow him to finally answer the critics and opposing coaches who doubt his arm strength.
Erickson has promised to emphasize down-field throws and aggressive play-calling -- and Garcia has embraced the changes.
"I'm antsy and wanting to be in the mix out there, but I also understand that the doctors know best," Garcia said. "They're pulling the reins tight, but I'm champing at the bit. ... It's hard for me to just sit on the side and watch, especially when I feel pretty good, but I have to listen to the doctors."
Garcia was hurt early last week while working out in Los Angeles. Weightlifting and running aggravated a degenerative disc in his spine, cutting off several nerves and effectively shutting down his lower back.
