Chargers running back Mike Tolbert defended teammate Vincent Jackson on Monday, saying the wide receiver got hurt in practice last week and didn't fake an injury in his first game back following a contract dispute. Jackson started Sunday night's victory at Indianapolis but limped off the field after two plays with a strained right calf. "I've played with him for two, going on three years now. I mean, he has so much heart that if he could play with it, he would," Tolbert said. "I saw him when he did it in practice a couple of days ago. It didn't look good but he was still out there trying to fight through it. Actually, some of the coaches had to tell him to calm down. "Luckily we didn't need him yesterday, but there's going to come a point in time when we will and he'll be ready," said Tolbert. Agent Neil Schwartz confirmed that Jackson got hurt in practice late last week. "It's totally absurd that he would fake an injury," Schwartz said.
