New England Patriots tight end Rob Gronkowski will be assessed on a week-to-week basis and has no fixed target for returning to action following an injury in Sunday night's defeat to Denver.
An MRI scan on Gronkowski has revealed no tear but that he suffered 'a bone bruise and sprain of his right knee' during the Patriots' 30-24 overtime loss to the Broncos, their first defeat of the NFL season.
The Patriots released a statement on Monday saying: "During Sunday night's game, Rob Gronkowski sustained a bone bruise/sprain of his right knee.
"His status will be evaluated on a week-to-week basis and listed accordingly on the practice participation and injury reports.
"There is no timetable for his readiness to return, which will be determined in the days or hours prior to the appropriate game. Any timetable reported prior to that final determination would be speculative."
Gronkowski has scored nine touchdowns this seasons for the Patriots who lead the AFC East division. They could seal that division with a win against the Philadelphia Eagles on Sunday, but the Patriots may be tempted not to rush their leading receiver back with tougher, post-season games to come.
