FOXBOROUGH, Mass. – No more end-zone spikes for a while from Rob Gronkowski.

A person familiar with the process said Monday the New England Patriots tight end expects to be sidelined for four to six weeks after having surgery for a broken left forearm. The person spoke to The Associated Press on the condition of anonymity because there was no official announcement.

Patriots coach Bill Belichick gave no update on the high-scoring, free-spirited tight end, who appeared to be hurt while blocking on an extra point late in the Patriots’ 59-24 win Sunday over the Indianapolis Colts.
