The rookie season of Cleveland Browns tight end Kellen Winslow Jr. may have ended after just two games.

The first-round draft pick is among several players who will be sidelined for a few weeks, or more, as a result of injuries in Sunday’s games. Others include New Orleans Saints running back Deuce McAllister and Baltimore Ravens tight end Todd Heap, both of whom were knocked out of games with a sprained ankle.

The Browns said Winslow will miss at least two months with a broken right leg, and that they might keep him out for the rest of the season. Winslow was injured trying to recover an onside kick late in Sunday’s 19-12 loss at Dallas.

Winslow is scheduled for surgery Tuesday and might need screws and plates inserted in the leg,

McAllister, who had his foot in a heavy orthopedic boot Monday, said he thought he’d be able to play soon – maybe even this coming weekend. But coach Jim Haslett said the Saints’ top rusher is expected to be out four to five weeks.

McAllister was injured on his third carry in the Saints’ 30-27 victory over the San Francisco 49ers. Defensive tackle Bryant Young grabbed McAllister’s ankle and the pain was immediate, causing McAllister to drop the football.

“I felt it pop,” said McAllister, who set franchise records in 2003 for yards from scrimmage (2,157) and rushing yards (1,641). “That’s why I dropped the ball.”

Heap, a two-time Pro Bowl selection, will miss two to four weeks with a sprained right ankle. Heap led the Ravens in receptions in each of the past two seasons and has a team-high 12 catches this year. The injury occurred late in the second quarter of the Ravens’ 30-13 victory over the Pittsburgh Steelers.

Pittsburgh Steelers quarterback Tommy Maddox will be out at least six weeks with a torn ligament and tendon damage in his right elbow, an injury that at least temporarily makes rookie Ben Roethlisberger the starter.

Maddox was injured while being hit in the third quarter of the loss in Baltimore.

Chicago safety Mike Brown, who returned a fumble 95 yards for a touchdown to spark the Bears’ 21-10 win over the Green Bay Packers on Sunday, will miss the rest of the season after tearing his right Achilles’ tendon. He was injured in the closing minutes of the game.

Priest Holmes missed much of the last quarter of Kansas City’s 28-17 loss to Carolina after spraining his left ankle, and the Chiefs aren’t sure if he’ll play against Houston this coming weekend.

Coach Dick Vermeil said after the game that he had been assured Holmes was all right, but on Monday morning he was told about the ankle problem.

A couple of other big names tried to shrug off injuries.

Edgerrin James, the Indianapolis Colts’ top running back, strained his hamstring in Sunday’s victory against Tennessee. He was running through some light drills Monday and was optimistic he would play this week.

“With me things always heal fast,” he said. “I might be good to go or play split duty or whatever. I can run and do everything.”

Deion Sanders is nursing a strained hamstring, but hopes to play for the Ravens on Sunday against Cincinnati.

“I’m feeling good. Look at me,” the 37-year-old Sanders said Monday, walking out of the Baltimore locker room without a noticeable limp.
