Andrea Bargnani, in breaking his silence, showed off his new black elbow brace, admitted his injury was “terrible’’ and said a timetable for his return from rehab is tricky because the ligament is completely torn. But even when Bargnani does return, it appears Knicks coach Mike Woodson has moved on. Woodson said the new-old small-ball lineup is likely here to stay — which means Bargnani becomes a bench player at best. The small lineup has Carmelo Anthony at Bargnani’s position at power forward and two point guards, Raymond Felton and Pablo Prigioni. It was the unit that thrived during last season’s 54-28 gem. With Thursday’s 117-86 victory over the Cavaliers, the Knicks are now 4-0 since Bargnani took a bad tumble eight days ago and was ruled out “indefinitely.’’ “The small lineup, we know that that works,’’ Woodson said. “Hey I don’t know if we’ll go away from it this time.’’ Bargnani spoke for the first time and said he doesn’t want to commit to a return date. An elbow surgeon interviewed by The Post said usually 3-to-6 weeks of therapy will do the trick. Bargnani said his doctors are talking to him more cautiously but confirmed there’s no plans for surgery. “I have no idea [on a return date],’’ Bargnani said. “It’s a ligament broke and you see how it heals and how strong the arm gets. You got to make sure it’s 100 percent. I really don’t know the timeline.’’ The elbow surgeon told The Post usually only baseball players and javelin throwers get the surgery — which could put him out one year.
