The shock of yet another injury followed by yet another surgery. The depression that set in. The long grueling rehab again. The tenuous first steps. The walking in a pool jogging on the side finally running. Participating in his first practice of training camp. And now getting into a game for the first time in two years. It has all been a physically and mentally taxing process for Terrell Thomas who Saturday night will take the field for the Giants at MetLife Stadium in preseason game No. 3 against the Jets. “I’m just excited to pack my bag to be honest with you’’ Thomas said adding he sees grandeur in the seemingly mundane. “I haven’t done that in a long time to pick out what cleats I’m going to put in there and see my jersey back on the shoulder pads before the game’’ Thomas said. “It’s a long time coming.’’ It has been since Aug. 22 2011. That’s the day Thomas tore his right anterior cruciate ligament in a preseason game against the Bears. After nearly a year of rehab Thomas last summer tore his right ACL again this time early in training camp. He had his second surgery in one year — the third time he needed reconstructive surgery on his right knee since 2005. He’s back now though and admits what awaits him this weekend will move him deeply. “Without a doubt’’ Thomas said. “It’s been a long journey a long hard one I went through a lot had to endure a lot and I think it’s just a true testament to my faith to my family to the fans and just to football what you sacrifice to this game. I think it will definitely be emotional.’’ Thomas’ mother Teressa Knox will make the trip from Southern California to attend her son’s comeback game. She also was in attendance two years ago when Thomas went down and out against the Bears.
