PRO FOOTBALL / DAILY REPORT : NFC : Keith Jackson Reports to Packers

Tight end Keith Jackson ended his three-month contract holdout and reported to the Green Bay Packers, who obtained him in a trade last March with the Miami Dolphins. Sherman Lewis, the Packers’ offensive coordinator, said he thinks Jackson could contribute as early as the Oct. 29 game at Detroit.

Jackson, an eight-year pro and five-time Pro Bowl player, caught 59 passes for 673 yards and seven touchdowns with Miami last season.

The Green Bay Press-Gazette reported that, under Jackson’s current contract, he will earn $661,765 for the next 10 games but is subject to $360,000 in fines for not reporting.

The San Francisco 49ers may make another change in the offensive line, meaning Elvis Grbac’s first start at quarterback could be behind a line that has new players in three of the five positions.

Right guard Rod Milstead has been bothered by a toe injury and Chris Dalman has been taking most of the snaps at practice in his place.

“Whether he will be able to start, I don’t know,” Coach George Seifert said. “I have all the faith in the world in Chris. I think he’ll do a good job if he starts.”

Earlier this week, Seifert benched center Bart Oates and replaced him by moving Jesse Sapolu back to center and inserting Kirk Scrafford into the lineup at Sapolu’s former left guard spot.

If Grbac and backup Cary Conklin go down with injuries, wide receiver John Taylor would step in as the 49ers’ “disaster” quarterback.

He took some snaps in practice this week and Siefert said, “John’s a good thrower and bright guy.”
