Turns out there were more injuries he was dealing with.
"It's not uncommon for stuff like that to happen. It's just little things here and there, the residual effects of two major surgeries and injuries, the wear and tear of playing throughout the season," Cushing said. "There were still some things bothering me a little bit. Just went in there and had real good success in both areas and looking forward to a very healthy and productive season."
This marks the third-consecutive season the sixth-year linebacker has gone under the knife. In 2012, Cushing suffered a season-ending left ACL tear; in 2013, the 28-year-old broke his left leg and suffered a torn LCL.
Cushing, a former Defensive Rookie of the Year, started 14 games last year and hasn't played a full season since 2011.
