Reggie Jackson cleared another hurdle Friday. It’s a small one, but it’s important nonetheless. Jackson went through his first full-contact practice of training camp, another step in his return from being shut down this summer on a 16-week protocol to manage the wear-and-tear on his knee tendinitis. During the first week of training camp, Jackson has been participating in only one of the two-a-day sessions. Getting through full contact with no pain or issues crosses off another milestone, but Jackson and Langston Galloway (knee bruise) are giving coach Stan Van Gundy optimism that he’ll have a backcourt close to full strength when the regular season starts. “I’m happy I’m feeling good even after this practice. I don’t know what to expect but my body is holding up so far and everything has been going according to the protocol,” Jackson said. “Everything has been going according to plan since we started the whole process in the summer. “I’m happy to be feeling good each and every day. The best thing is to wake up and be pain-free; even if (I’m) sore, it’s really body soreness and nothing with the knee. My legs may be a little fatigued because I’m getting back to the swing of things.”
