SANTA CLARA – -Wide receiver Jauan Jennings reported to 49ers training camp before Tuesday’s deadline for all players, a week after it was publicly revealed he’s seeking another contract extension or potentially a trade. “Jauan’s here and we expect him to be out on the field,” general manager John Lynch said. Coach Kyle Shanahan said Jennings has not requested a trade. — Ricky Pearsall’s hamstring injury during spring workouts “was bad,” coach Kyle Shanahan said.
