HAMPSTEAD, N.Y. — HEMPSTEAD, N.Y. -- After enduring the shooting pains of sciatica in his leg since last season, Tony Casillas decided yesterday to have back surgery that he hopes will allow him to return to the Jets in two months.
Casillas was to be a cornerstone of the revamped defensive line from his left tackle position, which is geared to stop the run. Instead, he is likely to miss the first four regular-season games, although he said before leaving for Dallas and surgery Wednesday that he expects to be ready inside of eight weeks.
