Gronkowski inactive for Patriots

FOXBOROUGH, Mass. -- Patriots tight end Rob Gronkowski is inactive for tonight's game against the 49ers.

Gronkowski, who broke his left forearm Nov. 18, had returned to practice for the first time on Friday, participating on a limited basis.

In addition to Gronkowski, the other Patriots inactive players are defensive back Derrick Martin, linebacker Tracy White, offensive lineman Markus Zusevics, defensive end Jake Bequette and defensive lineman Ron Brace.

The Patriots only had to declare six players inactive because they only have 52 players on their 53-man roster.

The 49ers are in a similar situation, and their inactive players are: safety Trenton Robinson, running back Jewel Hampton, linebacker Tavares Gooden, guard Joe Looney, receiver Mario Manningham and nose tackle Ian Williams.
