Report: Patriots concerned about Gronkowski, Michel playing vs. Packers

The New England Patriots are concerned about the availability of tight end Rob Gronkowski and rookie running back Sony Michel for Sunday night's game against the Green Bay Packers, sources tell ESPN's Adam Schefter.

Gronkowski has been dealing with a back injury and Michel's attempting to return from a knee injury. Both players are officially listed as questionable and will be tested pregame.

After missing the Patriots' Week 7 game against the Chicago Bears, Gronkowski returned against the Buffalo Bills in Week 8 to catch three of eight targets for 43 yards. The four-time All-Pro has just one touchdown this season while catching 29 passes for 448 yards.

Michel missed last week's game after suffering the knee injury early in the game against the Bears. The No. 31 pick in April's draft has 95 carries for 422 yards and four touchdowns as a rookie, adding four receptions for 31 yards through six games.
