FOXBOROUGH, Mass. — The Patriots must get used to missing Rob Gronkowski again.
The star tight end, who missed the first six games while recovering from surgeries, is done for the season after being placed on injured reserve Monday with a damaged right knee.
That experience could help the Patriots handle his absence.
"I'd like to think there's going to be some carryover there, not only (from) the first six weeks of the season, but the entire training camp as well," coach Bill Belichick said Monday.
Gronkowski was hurt in third quarter of Sunday's 27-26 win over Cleveland. He was hit by safety T.J. Ward after a 21-yard reception.
The Patriots were 5-1 while Gronkowski recovered from offseason operations on his left forearm and back. In the next six games, he led NFL tight ends with 37 catches and 560 yards receiving and the offense was much more productive.
Gronkowski suffered a torn ACL and damaged MCL, the Associated Press reported.
Browns coach Rob Chudzinski said he didn't know if Ward's hit resulted from a reluctance to hit and possibly incur a fine for helmet-first contact.
