FOXBOROUGH, Mass. -- New England Patriots linebacker Jerod Mayo has returned to practice Monday after missing all of last week for undisclosed reasons.

Mayo's return for a full-pads practice isn't the only good news for the Patriots on the health front, as rookie center Bryan Stork (out since July 29) and tight end Michael Hoomanawanui (out since July 27) are back on the field after being sidelined by undisclosed injuries.

Meanwhile, as previously noted, rookie receiver Jeremy Gallon (off physically unable to perform list) and defensive linemen Jerel Worthy and Ben Bass are practicing for the first time.

In his Monday afternoon news conference, Bill Belichick was asked about the 6-foot-2, 308-pound Worthy, a 2012 second-round draft pick of the Packers.

"He didn't play very much last year [but] played quite a bit his rookie year. He was a good player coming out of Michigan State, played well in a good conference against good people," Belichick said. "He has some athleticism and he has some size. We'll see how it all fits together for us. I'm happy to be working with him and we'll see how it goes."

While the returns of Mayo, Stork, Hoomanawanui and Gallon, as well as the additions of Worthy and Bass to bolster numbers, two notable absences at practice are starting right tackle Sebastian Vollmer and starting defensive tackle/end Tommy Kelly.
