Robbie Bosco, sidelined with injuries during his two seasons with the Green Bay Packers, says his arm is back in playing form.

"It's really exciting for me," he said Monday after working out at the National Football Conference team's indoor practice facility."The last two years, it's been frustrating. I've been throwing, but I've never been able to unleash it. Now, I'm able to do that."

The 1986 third round draft choice of the Packers had surgery on his shoulder in October of that year after having injured his right rotator cuff during his senior year at Brigham Young, and he reinjured the shoulder last November. He has spent most of this off-season in Green Bay, working with offensive backfield coach Willie Peete.

"I have the confidence that I can play," Bosco said. "I feel like my arm's ready, and just hopefully I'll get some breaks.

"I don't know if the arm will ever be 100 percent like it was. With all injuries, I think once you get injured or get cut on, it's kind of difficult for it to be exactly how it was. But I think it's real close."

Packer Coach Lindy Infante said the thinks Bosco is "throwing the ball fine."

"He looks like the velocity is there, and the timing's not bad," Infante said. "I think he's a little rusty, sure. But I think as he goes on that'll continue to get better.

"I think the important thing for him is just to get back in the rhythm of throwing to receivers and not worry so much about the finer technique things."

Bosco was among 17 players who turned out Monday for voluntary sessions held by the Packers.
