Rob Gronkowski has minor knee strain, Chris Johnson reportedly breaks tibia

The New England Patriots finally received some relief on injury news.

Tight end Rob Gronkowski is week-to-week with a minor knee strain he suffered in Sunday night's overtime loss to the Denver Broncos, a person with knowledge of the injury told USA TODAY Sports. The person spoke on condition of anonymity because the injury had not been announced.

Gronkowski leads the Patriots in both receiving yards (931) and touchdowns (9) and is one of the few remaining healthy targets for New England. The Patriots were without Julian Edelman (foot), Dion Lewis (knee, injured reserve) and Danny Amendola (knee), who could return in the coming weeks.

Patriots linebacker Dont'a Hightower is believed to have suffered a medial collateral ligament sprain in his knee and could miss a few weeks, NFL Network reported.
