Jenkins gives the Eagles a pass-rushing option inside. Last season, for Super Bowl champion Green Bay, he racked up seven sacks. He has 29 career sacks in seven seasons with the Packers, mostly as a defensive end. He moved to a three-technique end when the Pack switched to a 3-4 defense two seasons ago.
Eagles general manager Howie Roseman said Jenkins could play inside or out.
"On third down, he rushes from inside, and we think he makes a difference in that role," Roseman said. "In this defense, in this scheme, it really utilizes all his talents."
Bunkley, 27, was the Eagles' No. 1 selection in 2006. He recorded just six sacks in 76 career games, 52 of which were starts. Last season, he injured an elbow, missed a few games, and eventually lost his starting spot to Antonio Dixon.
The Eagles also have brought back free-agent linebacker Akeem Jordan.
They are virtually making over the defense for new defensive coordinator Juan Castillo. In the last few days they have added defensive end Jason Babin, cornerbacks Nnamdi Asomugha and Dominique Rodgers-Cromartie, and now Jenkins.
The team's embarrassment of riches and its free-spending week have turned the NFL upside down. In additition to the defensive players, the Eagles signed quarterback Vince Young, tight end Donald Lee, and wide receiver Johnny Lee Higgins.
Roseman was asked whether the Eagles still had room under the salary cap to continue making moves. He deferred to team president Joe Banner, who was sitting in the media tent.
"Hell, yeah," Banner said.
The Eagles have some long-term decisions to make in terms of money. Wide receiver DeSean Jackson is holding out for a new contract. Quarterback Michael Vick also is expected to get a new deal.
They could make more moves.
"Stay tuned," Roseman said.
Jackson isn't the only starting receiver not at camp.
Jeremy Maclin has yet to report. His absence has been excused, but the reason remained unidentified until Eagles coach Andy Reid described it as an illness.
"I really can't talk about it until he gets up here," Reid said. "And that's no pressure on him or I'm pushing. I just want what's best for him, and that's all I care about right now."
In March, Maclin was hospitalized with symptoms of mononucleosis. He said a month later after recovering that he had lost close to 20 pounds. By May, however, he said he had gained most of the weight back.
Reid would not say whether Maclin's absence was related to his March illness.
Danny Watkins missed his third day of training camp as contract negotiations for the team's top pick dragged on. Eagles officials have expressed frustration over the pace of negotiations with agent Eric Metz. Before camp, Watkins was penciled in as the starting right guard. Mike McGlynn was filling that role on Saturday. . . . The Eagles signed undrafted rookie wide receiver Jeremy LaFrance and cut rookie running back Noel Devine.
